Query: Don't know how Grandpa tolerated it

I picked this stuff up on a trip and used most of the can before throwing it out. For me the negative effects were cumulative... at first it worked fine (and I felt tough and old school), but after a couple of months I realized my skin had become really tight, dried out, and sensitive. The problems disappeared after my wife replaced the Barbasol with some fancy stuff. Guess I'm just a pampered wuss.
