Clutch life is very driver dependant. If you don't slip it all the time, drive in stop and go traffic, or other high clutch wear scenarios it can last 150k miles+, OTOH, if you sit at traffic lights and hold your car against the hill, and abuse it you can fry one quite easily.

My GF sold her '89 Accord @ 184k miles, original clutch, and still holding well.
