Cremation, don't want any chance of waking up being buried alive.
Since people will never stop dying think a waste of a lot of real estate that will need to continue to grow to meet demand. Seems like a waste to me. Some people come visit ya for a while and then that eventually stops so your body is in the ground, nobody visits, your dead anyway so who gives a fuck, burn everybody, save some land, throw da ashes wherever ya wanna be.
