Never really thought about shaving (I think I am just past that age mark where it became fashionable) but do trim where necessary. However, I did note that most (all) of the males in the crew we had formed last trip were more shaved than I was. Don’t think I will change (though I rarely have kept that promise in other things!) but if you are looking for the trend it would be less hair....IMHO. Do what you want to do!
