240V will give you a jolt, but it's really not that bad, at least if it's quick. I grew up in the UK and got my fair share of 240V shocks as a kid - from bare feet touching bare wires/connectors under the table, to me lighting up a small dolls house light bulb by poking stripped pieces of wire into a wall socket, while holding the other end with bare fingers onto the light bulb! I'm not dead yet!
You can even get a 480V shock if you short yourself across two wall sockets wired to alternate phases (+240V, -240V).
