What do men do

I walked into work the other day with my giant purse filled with lots of treasures and then saw a guy walking in carrying nothing, I thought how does he travel with his items. Where is his day planner, where are his books, chapstick, etc. I realize having 2 books in my purse is more than most or the fact that I can probably find 6 lipglosses in my bag at any given time but seriously, men how do you travel with so little?
