Personally, I only put I believe 2 items and a short description of each activity (1-2 sentences), if you have a laundry list, i'd say go for it dude... but don't get too crazy now, cause the more you put, the more they can ask on an interview... I actually found that question a bit difficult myself, since I don't work at an old age home or with the neighborhood crime watch and such.. Hope that helps tho...
