I'm a biker/hiker. I use two types of outdoor gear -- motorcycle stuff and hiking stuff. This Winter I surveyed my closets, identified what's missing and filled gaps. I just added two pieces which make me smile -- a handsome hiking hat and a black leather motorcycle vest. Both are attractive and useful.
Hiking in the sun, I wondered afterward why the top of my head hurt. Sunburn! In a spot where my hair is getting sparse. I never expected that and never thought to put sunscreen on the top of my head. I assumed (incorrectly) that my scalp was protected by a robust head of hair. Ahh... age. Our minds think our bodies haven't changed but look in the mirror, buddy. It's happenin'.
So a hat is necessary. To keep my head from getting sunburned. By the way, anyone who uses the phrase "bald patch" is dead to me, so be careful with your comments. :-)
My new "Street & Steel" motorcycle vest is also fun. It conveys the right kind of style that helps one fit in with a crowd of bikers, which is where I find myself. When in Rome...
