Do house electric wires harm your health?

I've been changing out lights, switches and electric plugs and a few times neglected to turn off the circuit breakers. I've been zapped a handful of times and it HURTS but I'm curious if the amount of electricity causes any serious or long term damage.
Please don't respond with moronic answers such as, of course its bad for you its electricity or that it CAN kills you (though if it can I'd like to know that). Consider that I've already been zapped a few times so I'm asking what long term damage might have been done to me under these circumstances.

Thanks!

Answers:
If you are fit there should no lasting effect. but you do take your life in your hands when you are taking belts of electricity, if water or wet is involved it can and will probably kill. you no doubt have survived and that's good, but you have the electricity switched off and isolated, when working on it.
In the UK it is now a criminal offence to work on domestic and commercial wiring without qualifications, you need to be an Electrician, I still do my own but I isolate first.
Be Safe, and Good Luck!

NO. I get zapped all the time when I work on the electrical wiring without turning off the circuit breakers. No problems except some slight tingling in my arm and numbness soemtimes.
