Why We Fall As We Age
These fast twitch muscles keep us from falling and breaking something as we age. They allow us to keep our balance if we slip on something or step off a curb without noticing the drop. They allow us to quickly apply the brakes to avoid a catastrophic fall. After the age of 70, if you fall and break your hip, it could be fatal or, at minimum, be a long, painful recovery period that reduces your quality of life.
