Weight-bearing exercises are good for most.
But are you asking for someone in the family? Male or female? Dairy-eater or not? Estrogen
-taker or not? All of these are important factors as are age, race, family history, lifestyle, etc. If i had to name one activity for everyone, it would be walking. Daily. Throughout the day. We hope this inspires all of you to start now and keep going for 80 years.
