im pretty sure everybody has a random health facts or two...
post them here, they're fun to read....

i found a lot (all taken from http://popularerrors.com/category/health.s html) :

-A person will burn 7% more calories from walking on hard dirt than from walking on pavement.

-A bit of dark chocolate once a week is actually good for you.

-You will burn more calories sleeping than watching TV.

-A person is more likely to get heat stroke on a hot, dry day than on a warm, humid day. This is because after the humidity rises over 70%, sweating becomes a non-effective way to cool down.

-A person can die from laughter, there have been several cases in the past.

try not to repeat facts because then i gets boring
