Do I get a cold if I get cold?

Cold weather has nothing to do with catching or fighting a flu virus. People who go on expeditions to the North Pole spend months there and never get a cold, and there are no documented research results that connect the activity of viruses to cold weather. The efficiency of the immunity system is also an issue of study, but no results of diminishing capability to fight viruses as a result of cold weather has been confirmed.

What has been confirmed, though, is that viruses are transmitted when people crowd up in closed places, and when they don’t wash their hands after high-fiving other sick people and go on to pick their noses. Also, when people kiss each other (breathing out in each others' faces while switching from cheek to cheek repeatedly) that also makes people get a cold.

The best way to prevent getting "the flu" or "the cold" is not by wearing heavy clothing during the winter season, but rather by washing your hands.

Other interesting health facts include:
- There is no test for all cancer. There aren't even a group of tests, whether blood tests or X-rays that can tell you you're a 100 per cent free of cancer. Doctors can look for cancers if they suspect it, and a lot of cancers can only be discovered once they have spread all over your body.

– People who have HIV can now live almost just as long as healthy people. Even those with full-blown AIDS can usually be treated and survive for decades.

– The best way to tell if someone has B12 deficiency is NOT by checking their B12 level, but rather by checking the level of MMA (methylmalonate), which goes up if B12 level is low.

–People can have diabetes and high blood pressure and start having damage in their eyes and kidneys for several years before having symptoms or being diagnosed.

– Every 30 seconds, one person dies from malaria, an easily-treatable infection.
