We've probably all heard stories about how eskimos would send their old folks off on ice floes. But is there any evidence that's true?

We have? I’ve definitely never heard that…

“But yes, in the past some Eskimos did kill old people when circumstances were sufficiently desperate. Pressure from missionaries and national authorities, improving economic conditions, and no doubt evolving notions of acceptable behavior among native peoples eventually brought an end to the practice. The last reported case was in 1939, but the custom was a rarity long before that. In any case, the common perception of taking Granny out to the nearest ice floe and setting her adrift is wrong. I can’t prove it never happened, but it wasn’t the usual method.

Senilicide (the killing of old people) was never universal among Eskimos. It was common in some parts of their range but more so among the Inuit (Greenland to Northern Alaska) than the Yuit (western and southwestern Alaska). Even among the Inuit, some groups found the custom repugnant.

Where it was practiced, senilicide was rare except during famines. As long as there was enough food to go around, everyone got their share, including the relatively unproductive. Given that the usual diet consisted of fairly dependable catches of caribou, fish, and sea mammals, many years could pass between episodes of scarcity. Considering the dangers of hunting, the old and infirm who weren’t expected to hunt could outlive a hunter in his prime.

On the other hand, when food did run short, the old and sick were looked upon as drains on the community’s resources. Sometimes they were killed – thrown into the sea, buried alive, locked out in the cold, or starved to death. Far more commonly they were simply abandoned to die. The victim might be taken out in the wilderness and left there, or the whole village might pick up and move away while the old person slept. If the villagers were unexpectedly restored to prosperity, they might go back to rescue those left behind. An abandoned person would also be welcomed back as a full member of the community if he could manage to make his way back to the village on his own. But usually he couldn’t. ”

From The Straight Dope

I thought it happened voluntarily when they wanted to die. Perhaps I read too many novels.

As far as I can tell, that’s true. I KNOW it’s true that the old people of several American Indian tribes, when they got too old to be of use to the tribe any longer, would wander off into the wilderness to die.

I’ve heard about a tribal community alive today that kills or used to kill their old people, or killed people before they got old, I’m not sure which. I think it was on a TED lecture if anyone remembers, death-by-spearing was the way to go for the members of the tribe.

It certainly is an interesting concept. I can’t say I’ve ever heard of it happening in real life. Anyone remember the movie Logan’s Run?

And Soylent Green for that matter!

I think that is totally unbellievable.
