Sequence your very own genome.
In 2003 the genome project sequenced the first human genome. Now in 2007 this service is available to the general public where each person has the ability to sequence their own DNA and find out what disease lurks from within. So far two companies have come out with this service: https://www.23andme.com/ - This site is Google driven and costs $999 and a swab from your mouth to get you your results. http://www.decodeme.com/ - A little cheaper with $985 based off of a a bio-pharmaceutical company.
