For me, the most interesting thing about my 23andMe results was that my Y chromosome confirmed the family rumor that my grandfather was not actually the son of his father. If enough people join 23andMe, it&#x27;s possible that I may find my actual relatives.<p>Many people find this sort of thing creepy. I&#x27;m OK with it.<p>And on an even-more-personal note, as a guy with long hair, it was exciting to learn that I didn&#x27;t have the male pattern baldness gene, even though my maternal grandfather was bald as an egg by the time he turned 40.
