 All right, my friends, I have a longevity test you can do at home, and it only takes 10 seconds. It's called the Flamingo Test. All you got to do is balance on one leg for 10 seconds, then do the other leg so you look like a flamingo. I don't think I could pass this. The study was published in the British Journal of Sports Medicine. Over 20% of the study participants failed this Flamingo Test.
