Look at me! I have hair! Luscious, full hair!
Based on the goatee, sideburns, and flannel shirt, this is clearly from my undergraduate days. It was really thinning out on top by graduate school. In fact, it was that first winter of grad school that I chopped it down to a Caesar-style cut for the first time and discovered just how much my hair had thinned and my hairline had receded.
So if I had this much and it looked this full and I had facial hair, it was undergrad. Maybe sophomore or junior year.
Ah, the glory (hairy) days.
