I really don't understand paying to go some where and move things, (like a gym), go get a job tending block or shoveling shite. At least then you can make some money.
Oh I don't know... because of the scenery? Pay to work out and enjoy the scenery in the A/C or get paid min wage to shovel poop in the blazing heat and look at other dudes shoveling poop, it's tough call for sure.
Yoga is awesome!
