I have 3 sisters and 2 brothers. One of my sisters (64) is healthy and active/spin bike and a joy to be around. My younger brothers (52 and 60) sit in front of the TV, never exercise. My two older sisters (65 and 67) haven't exercised for decades and miserable people in general. My 65 year old sister in particular is probably listed on the 10 most miserable people in the US list. As a kid growing up she never ran, biked or played like a normal kid and as an adult is bitter about not regaining full movement after a knee replacement 10 years ago of which she did not pursue PT after the replacement. But none of my brothers or sisters can keep up with little old me age 62. Not even close.
