GANHEI ESTA MENSAGEM ...


Receita de Dona Ca
cilda
(imagem da net. para ilustrar.)
Dona Cacilda é uma senhora de 92 anos, miúda, e tão elegante, que todo dia às 08 da manhã ela já está toda vestida, bem penteada e discretamente maquiada, apesar de sua pouca visão.

E hoje ela se mudou para uma casa de repouso: o marido, com quem ela viveu 70 anos, morreu recentemente, e não havia outra solução.

Depois de esperar pacientemente por duas horas na sala de visitas, ela ainda deu um lindo sorriso quando a atendente veio dizer que seu quarto estava pronto. Enquanto ela manobrava o andador em direção ao elevador, dei uma descrição do seu minúsculo quartinho, inclusive das cortinas floridas que enfeitavam a janela.

Ela me interrompeu com o entusiasmo de uma garotinha que acabou de ganhar um filhote de cachorrinho..

- Ah, eu adoro essas cortinas...
- Dona Cacilda, a senhora ainda nem viu seu quarto... Espera um pouco...
- Isto não tem nada a ver, ela respondeu, felicidade é algo que você decide por princípio. Se eu vou gostar ou não do meu quarto, não depende de como a mobília vai estar arrumada... Vai depender de como eu preparo minha expectativa.

E eu já decidi que vou adorar. É uma decisão que tomo todo dia quando acordo.

Sabe, eu posso passar o dia inteiro na cama, contando as dificuldades que tenho em certas partes do meu corpo que não funcionam bem...
Ou posso levantar da cama agradecendo pelas outras partes que ainda me obedecem.

- Simples assim?
- Nem tanto; isto é para quem tem autocontrole e exigiu de mim um certo 'treino' pelos anos a fora, mas é bom saber que ainda posso dirigir meus pensamentos e escolher, em consequência, os sentimentos.

Calmamente ela continuou:
- Cada dia é um presente, e enquanto meus olhos se abrirem, vou focalizar o novo dia, mas também as lembranças alegres que eu guardei para esta época da vida. A velhice é como uma conta bancária: você só retira aquilo que guardou. Então, meu conselho para você é depositar um monte de alegrias e felicidades na sua Conta de Lembranças. E, aliás, obrigada por este seu depósito no meu Banco de Lembranças. Como você vê, eu ainda continuo depositando e acredito que, por mais complexa que seja a vida, sábio é quem a simplifica.

Depois me pediu para anotar:
COMO MANTER-SE JOVEM


1. Deixe fora os números que não são essenciais. Isto inclui a idade,o peso e a altura.
Deixe que os médicos se preocupem com isso.

2. Mantenha só os amigos divertidos. Os depressivos puxam para baixo.
(Lembre-se disto se for um desses depressivos!)

3. Aprenda sempre:
Aprenda mais sobre computadores, artes, jardinagem, o que quer que seja. Não deixe que o cérebro se torne preguiçoso.

'Uma mente preguiçosa é oficina do Alemão.' E o nome do Alemão é Alzheimer!

4. Aprecie mais as pequenas coisas.

5. Ria muitas vezes, durante muito tempo e alto. Ria até lhe faltar o ar.
E se tiver um amigo que o faça rir, passe muito e muito tempo com ele ou ela!

6.. Quando as lágrimas aparecerem, aguente, sofra e ultrapasse.

A única pessoa que fica conosco toda a nossa vida somos nós próprios.

VIVA enquanto estiver vivo.

7. Rodeie-se das coisas que ama:
Quer seja a família, animais, plantas, hobbies, o que quer que seja.
O seu lar é o seu refúgio.

8. Tome cuidado com a sua saúde:
Se é boa, mantenha-a.
Se é instável, melhore-a.
Se não consegue melhorá-la , procure ajuda.

9. Não faça viagens de culpa. Faça uma viagem ao centro comercial, até a um país diferente, mas NÃO para onde haja culpa

10. Diga às pessoas que ama que as ama a cada oportunidade.

Muitas vezes é preciso agente parar e pensar em nós.
Cuidar mais de nós mesmos...
trocar de penteado, passear pelas ruas da cidades, curtir a linda luz, que está maravilhosa no céu esta semana.
Cheia e romantica.
Ganhei esta mensagem da minha querida Marcia e decidi compartilhar com você meu amigo(a).
As vezes, as coisas ficam adormecidas dentro de nós. E precisam serem lembradas.
Com muito carinho
Sandra

Real vs Placebo Coffee

Coffee contains caffeine, and as everyone knows, caffeine is a stimulant. We all know how a good cup of coffee wakes you up, makes you more alert, and helps you concentrate - thanks to caffeine.


Or does it? Are the benefits of coffee really due to the caffeine, or are there placebo effects at work? Numerous experiments have tried to answer this question, but a paper published today goes into more detail than most. (It caught my eye just as I was taking my first sip this morning, so I had to blog about it.)

The authors took 60 coffee-loving volunteers and gave them either placebo decaffeinated coffee, or coffee containing 280 mg caffeine. That's quite a lot, roughly equivalent to three normal cups. 30 minutes later, they attempted a difficult button-pressing task requiring concentration and sustained effort, plus a task involving mashing buttons as fast as possible for a minute.

The catch was that the experimenters lied to the volunteers. Everyone was told that they were getting real coffee. Half of them were told that the coffee would enhance their performance on the tasks, while the other half were told it would impair it. If the placebo effect was at work, these misleading instructions should have affected how the volunteers felt and acted.

Several interesting things happened. First, the caffeine enhanced performance on the cognitive tasks - it wasn't just a placebo effect. Bear in mind, though, that these people were all regular coffee drinkers who hadn't drunk any caffeine that day. The benefit could have been a reversal of caffeine withdrawl symptoms.

Second, there was a small effect of expectancy on task performance in the placebo group - but it worked in reverse. People who were told that the coffee would make them do worse actually did better than those who expected the coffee to help them. Presumably, this is because they put in extra effort to try to overcome the supposedly negative effects. This paradoxical placebo response reminds us that there's more to "the placebo effect" than meets the eye.

Finally, no-one who got the decaf noticed that it didn't actually contain caffeine, and the volunteer's ratings of their alertness and mood didn't differ between the caffeine and placebo groups. So, this suggests that if you were to secretly replace someone's favorite blend with decaf, they wouldn't notice - although their performance would nevertheless decline. Bear that in mind when considering pranks to play on colleagues or flatmates.

It looks like science has just confirmed another piece of The Wisdom of Seinfeld:
Elaine: Jerry likes Morning Thunder.
George: Jerry drinks Morning Thunder? Morning Thunder has caffeine in it. Jerry doesn't drink caffeine.
Elaine: Jerry doesn't know Morning Thunder has caffeine in it.
George: You don't tell him?
Elaine: No. And you should see him. Man, he gets all hyper, he doesn't even know why! He loves it. He walks around going, "God, I feel great!"

A Weighty Issue

The BBC asks - "Why are fat people abused? Why is "fattism" seen by many as an acceptable prejudice?"


Psychoanalyst Susie Orbach explains or tries to:

Often the assumption is that overweight people have lost their self-control. That frightens society because there is so much emphasis on being slim, she says.

"Often it's not the larger person's excess weight that is the problem, it's the other people's obsession with being thin. Most people want to be slim, but this perceived physical perfection is difficult to hold on to and they fear losing control of it. Women and men can be on diets their whole lives and it's utterly miserable. They project that fear and unhappiness on to people who are bigger and that often translates into abuse and attacks. It's a way of people disassociating themselves from what they fear the most - getting fat."

But this is pure psychobabble. Like saying that all homophobes are repressed homosexuals, it's satisfying, but not true. (Although...) Most people fear cancer, but we don't "project" this fear onto others by accusing them of having it, or hating people who do have it. Orbach seems to still adhere to the Freudian idea that obvious explanations of human behaviour are usually wrong, and that people's true motives are unconscious, and usually embarrassing.

The truth is more straightforward. For various cultural and historical reasons most of us prefer thinness to fatness. And crucially we see weight as something people have personal control over. Far from fearing that overweight people have lost their self-control, we think they choose not to use it.

This is why it's "OK" to not like fat people; just as it's OK to not like criminals, selfish people, racists, etc. It's "their fault". Whereas it's not OK to make fun of people with one leg, deaf people, people with genetic disorders and so on. They "can't help it".

But there are grey areas, and this is where it gets interesting. People with cancer deserve sympathy... unless perhaps it's "their fault" for getting it, e.g. lung cancer from heavy smoking. Paedophiles deserve severe punishment... unless perhaps it's not their fault. How could it not be? How about if they developed a compulsive urge to view child porn due to the medication they were taking for Parkinson's disease? Or if they started abusing their daughter because of a brain tumour?

This is why one Kathryn Szrodecki, who campaigns on behalf of overweight people, is quoted by the BBC as saying
"We're simply not all built to be slim, our genetic make-ups are all different."
In other words: actually it's not our fault. Likewise, conservatives say homosexuality is a choice; liberals say it's something you're born being. Both sides implicitly agree that if something's not a choice, it's wrong to treat people badly for it. In an attempt to destigmatize clinical depression, a billboard famously proclaimed that "Depression is a flaw in chemistry not character" - it's not your fault.

The trend at the moment is towards things being no-one's fault. It's happened to everything from drug and alcohol addiction to antisocial and criminal behaviour (as ADHD, Conduct Disorder, Personality Disorders, etc.) By contrast, I can't think of anything which has moved in the other direction. Of course, not everyone accepts that, say, addiction is a disease. Many people still think it's a moral issue. But they're on the back foot. The wind is blowing in the other direction.

We can expect even more of this in the future, as neuroscience and genetics find biological causes and correlates of ever more behaviours. Brain scans in particular have a seductive allure when it comes to making things seem to be outside the sphere of choice. As for how valid any of this is, well, that's another story. But if the fat acceptance movement wants to advance their cause, finding a few fMRI scans might be the best way to do it.
