I like:

LAUGHTER Remember the last time you laughed so hard you couldn't stop? Good. Do it again. Laughter increases blood flow by causing the inner lining of blood vessels (the endothelium) to expand, according to a small study of healthy moviegoers who were shown both funny and distressing clips from films and then tested for the physical effects of each. With laughter, blood flow increased 22%; under stress, it decreased 35%.

I do that almost every time I read this stuff.

Researchers theorize that mountain dwellers may be strengthened by a lifetime of arduous hiking and better adapted physiologically to cope over the long term with high-altitude oxygen levels and other cardiovascular stresses.

Maybe they use less oxygen, oxidize less stuff?

Regards.
