I'm 13 right now and the first time I was shocked by 220v ac was probaly when I was 5. Since then, I've been shocked quite a few times. Electricity here is 220v.

So far you have been lucky. The amount of pain iis dependent on how much current passes through you and where it passes. With electrodes you are minimising the resistance of you and so is much more dangerous than a casual schock.
You must have at lease a 1M resistance in seriese with electrodes.

Anything from a few hundred ohms to tens of kilo ohms, depending on moisture.

Oh I thought it was about 400k for females and 600k for males.

EDIT
So I guess I can use myself as a pull-down reistor if I run out of resistors!

thnx for all ... i was using DC power supply ...but now im using 9v batteries  and  isolate myself and my work from electricity.... but i got a sequre wave on the output of AD620 ..... my friend told me that the transistors reched saturation region so change the input voltage to 3v ....but i see most of researchs used 12v as input ....any one have used AD260 before can help me ?? i will make a new topic for that ...thnx again
