my 16 yo sister died two weeks ago tommorow. when i saw her dead just minutes after she had died, the first corpse i'd ever seen, one the things that popped into my head was how happy i should be to be alive. she died from cystic fibrosis, a disease that will most likely be eradicated completely in coming years by gene therapy &c. We should be thankful to live into old age, nevermind immortality, although I'd be surprised of anyone to refuse it considering our standard of life in the developed world.
