Would you have the nerve to milk a rattlesnake? Would you be able to climb a 2000ft tower to change a light bulb?

I've twice spontaneously picked up Garter snakes - the first time, it did a lot of wriggling so I set him down, the next one seemed curious about me passed me a few times on the rail so I spoke to him and before I picked him up and he stayed calm....not sure about a rattlesnake though....
