There's a 60 second test that determines how old you are and most people over 40 will fail it. It's called the Old Man Test. 1. Stand barefoot with your shoes and socks in front of you. 2. Lift one foot. 3. Put on a sock, then a shoe, tie it. Foot never touches the ground. 4. Switch sides. Do the same thing. As you age, balance becomes the canary in the coal mine. The good news is you can improve it at any age. - Don't be excessively fat - Build lower body strength using single leg exercises - Walk heel to toe across the kitchen - Stand on one foot while brushing your teeth - Get off the couch without using your hands - Lift weights 3x a week. Try it out and let me know in the comments if you passed or failed.
