Forget about the present. Delve into your past history or look for future illnesses and diseases that could hit you. I'm not kidding you; simply send a cheek swab to 23andme and for a fee they will send you a complete analysis of your DNA. They can tell you your ancient ancestry, They can tell you what diseases you're inclined to, They give you a "Gene Explorer" that allows you to do a search in your genome to find out if you have a certain gene.
