re: Using the Moon - as a cemetary
One perk, living in retirement on the Moon, could be a good
value on a cemetery plot- and not just a gram, but the whole nine yards. Hell, they might pay your kin in order to "take your water".
The pharaohs of Egypt never had it so good- 5000 years would be nothing- try a million, maybe if lucky a billion years.
And I personally, would no problem being buried near some radioactive waste. I think I would prefer it- it would be like being buried with a clock.
