I know, personally, of one reincarnation memory-recall, in which the subject, a Statisticalist, voluntarily discarnated by lethal-gas inhaler in a private room at one of our local maternity hospitals, and reincarnated twenty years later in the city of Jeddul, three thousand miles away.

"A Breath of Prairie and other stories"
Will Lillibridge
At the same great height I found that even without my oxygen inhaler I could breathe without undue distress.
