Ridiculous. I cut my teeth on high voltage. When I was in high school,
10,000 volts was not a problem. I am seeing a generation raised on 5
volts, very happy on 3.3 volts and looking forward to 2 volts. The
secret to high voltage is don't get scared and keep your grubby hands
out of it. I could teach a gorilla to handle that. The OP can do what he
wants and live to tell about it if he is simply careful. 7000 volts
doesn't jump very far. It's not like it's going to stalk him in the
night or anything.
