How to make it past every road block and live to 100—
Age 25—don’t do drugs, and cross the street safely!
Age 45–don’t smoke!
Age 70–Eat healthy and exercise!
Age 90–Don’t fall down and break your hip; be graceful and watch where you’re going!
That’s it! You’ve made it to 100!
Is it really that simple? I thought of this myself and it seems like a good hypothesis
