 It's kind of like when you touch fire and it burns. Ouch, that burned. You don't have to really do it again. Sometimes you do going, well, if I get my hand wet, I can probably reach into that fire for just a second. And then you find out how long you can reach into the fire with a wet hand. And then you continue to pick up data. Maybe if I put a welding glove on, I can reach into the fire for a little longer until the welding glove catches on fire.
