Sure. Everyone knows they should exercise more, but what tips the balance in general, and what tips it on a day when you feel like crap and would rather surf Hacker News or go back to bed? Friends or family you exercise with, a loved one getting sick, a realization that your body doesn't work as it used to when you throw your back out, a gym opens up near your house? Which straw strengthens the camel's resolve? I wouldn't say that 23andme data was the only or even main factor, but for someone with a scientific bent, having read a few studies that showed an x% improvement in odds on avoiding a disease that I didn't want in populations with specific genes that I shared provides an extra bit of motivation on some days. I already exercised, but progress in health isn't binary, it's about frequency and repeated effort. Miss a significant percentage less workouts over a few years and the $99 on genetic testing easily pays for itself.
