Why do electricians touch live wires but don’t get electrocuted?

I think electricians do get shocked every now-and-then.  No doubt about it.    If you have to work around anything dangerous day-in-and-day-out, you gradually get a bit lackadaisical -- maybe even lazy -- and you don't take all the precautions you should.   It's like asking a pro race-car driver why he/she doesn't worry about crashing when driving around a track at c. 200 mph.  You kind of get desensitized to all the dangers after a while...

I was surprised to see that professional electricians didn't seem to turn off the power when working on low voltage (house wiring, 100 - 250 VAC) circuits. They know not to touch bare hot wires if possible, and if so, then not while grounded. But if they do get shocked, it's generally only a surprise, and not fatal. With high voltage circuits, they absolutely can die from touching one wire, even if somewhat insulated, and turn the power off.

they handle the the wire by the insulation not the bare wire ..havent you seen an electrician not wear rubber gloves before ..

For safety reasons, they have to shut off power to work on the wires.

Because they are not grounded so there is no path for the electricity to flow through them. Christin K is wrong, watched my Uncle touch live wires as a kid when he replaced a light switch in my room. 

They don't touch live wires. they turn off the power before touching any wires--it's just common sense. 

small jobs will as a rule, turn off the live power.You do the work, and then turn it on again.I'm not a large power guy

Because they weared a special type of gloves.

They have rubber gloves, they can still get a slight burn but they don't get sent flying.
