And what do you do?

I own a plumbing heating and airconditioning business. Been doing it for 23 years. I regularly trouble shoot, and engineer systems for houses. Also work on Commercial refrigerators, and did computer room air conditioning for companies like MTV, HBO, Morgan Garaunty bank, and the Dow Jones.I am also a master sheet metal layout mechanic. I can cover the average person in sheet metal if they want. I've done a gargoyle in copper on top of a west side Manhattan apartment building.For hobbies, I have too many to list, including ameture radio, anything R/C, and playing piano for my church (Christian rock). I design, build and fly R/C planes. I fish, drag race, build my own boat and car motors, also ride motorcycles. Took a few flying lessons too
