Hey, why not? I rent a nice apartment and also think I might one day live in, well, not a van, but perhaps a RV or trailer of some sort. For me, buying a house is the LAST thing I wanna do. Folks think they own them. Unless you bought the thing hands-down, you DO NOT own the place. And the property taxes and constant repair/maintenance headaches aren't much worth it, either.
"Oh, yeah. I am building my retirement." Oh, brother.

Get fucked. If men didn't marry, buy dumb houses big enough for offspring and a hot tub in the backyard and stayed away from idiotic vices like drugs and booze, most would have more than enough for "retirement". And that's if you make it to such an age. Fact is, us Getbiggers are high test dudes who will most likely crash to the floor in writhing pain from a heart attack sooner rather than later.
And no one will give two shits. So jam your tunes, lift some poundage and bang some broads.
