This is all well and fine, but without insurance as a licensed business when you get hurt and need medical attention (which happens) homeowner's insurance will cover it--once. Next time is quite possibly on you, so that could be a $12,000 bill. It could be $2,000, or it could be $175,000, such as if you get a chain in the leg.
I'm certainly in support of people doing what they love and being ambitious, which is way better than playing video games which usually get you nowhere--speaking of that, when younger guys (like 25 or 27 years old) tell me about their new game deck I ask them what they play. If they ask me I tell them, "I'm currently playing
Chainsaw Hero. The graphics are
insane, but if you die in the game you die in real life."
(by the way, I just "leveled-up" and was able to buy a MS 881 with 41" bar)
