DON'T LET YOUR JOB KILL YOU
Seriously--and more specifically, if at all possible, work with people who support you:
"Do you work with a bunch of jerks? Well, you might not be lying if you stand up and shout "this job is killing me!"
The risk of premature death is greatly reduced for people who report high levels of social support at their job, according to a new study published in the May issue of Health Psychology. Workers between the ages of 38 and 43 were mostly likely to be negatively affected.
Translation: If you want to live long and prosper, work at a company filled with people you actually like."

AND DON'T STAY AWAKE ALL NIGHT WORRYING ABOUT IT, EITHER
Because that slows your metabolism:

"Sleep deprivation makes the day drag and appears to put a drag on metabolism too, causing the body to use less energy, according to a European study. The results, reported in the American Journal of Clinical Nutrition, add to evidence that sleep loss can promote weight gain -- not just by boosting hunger but also by slowing the rate at which calories are burned.

The study suggests that getting plenty of sleep might prevent weight gain, said Christian Benedict of Uppsala University in Sweden, who led the study.

"Our findings show that one night of sleep deprivation acutely reduces energy expenditure in healthy men, which suggests sleep contributes to the acute regulation of daytime energy expenditure in humans," he wrote."

And by the way, just as an aside, on a totally different topic:  this is an excellent book, by an excellent author, Sarah Dessen.  It's officially classified as a "teen" book, but honestly, this and all her books can be read by anybody and will absorb anybody.  A real page-turner, filled with insights into the human condition and life that will interest teens, parents, and anybody else. 

It's called "What Happened to Goodbye."  I highly recommend it.
