Repeating myself: For 100,000 years the average life expectancy of humans was 34, including the year 1900. And life was no picnic for those who lived a long life. If you broke something you limped or were otherwise impeded, crippled or disfigured. If a fungus, skin infection or something grew on you somewhere it stayed until you died, likely disfiguring you at the worst and making you not so hot at the best. If your tooth got knocked out you looked like shit the rest of your life, unless you were lucky enough to get a wooden or metal one. If your eyesight gave out, you bumped into things. If you relied on your keen eyesight for making a living (most of us do), such as a cobbler, blacksmith, etc., your ability to be gainfully employed and feed yourself/family was greatly impacted.
And in some cultures, if you were really old and feeble, or just kinda old and feeble, they took your sorry ass out into the wilderness to die. Nothing personal.
And forget about signing up for food stamps, welfare, unemployment, social security or disability.
So my irrational end-of-timer, dumb-ass, friends, pick a time period in which you think things were so much better. Go ahead, make my day.
