Sarcasm aside, there are many people over 55 who are not as capable as people who are younger. Most 55 years old's do not have the strength, agility, and quickness of a 20 or 30 year old. That's just a fact of life. Yes, there are a few over 55 who are physically fit. But, most, even if physically fit do not have the same abilities of a younger person. That is the reason that woman should never be seated in exit rows. They just don't have the inherent strength to handle aircraft emergencies. The female flight attendants go through extensive and rigorous training and even they may have trouble with strength related emergencies. Of course, we are all brave and nonchalant until the plane goes down.
