Earlier cultures dealt with the problem more mercifully IMO. When the time came it was part of the social contract in many societies to leave old folks alone in the wilderness to die with dignity of exposure, starvation and thirst -- a much kinder and quicker fate than being left to the not-so-tender mercies of minimum-wage airheads who entertain themselves by placing bets on which of their charges will wet or soil themselves first.
I'm reaching that time of life. Thank God I haven't given all my guns away!
Plenty of earlier cultures revered the elderly and took care of them with kindness and respect!
