You are not crazy! For me, I always feel great after getting the stubble off my face. I feel nice n clean!I may be a little nuts, but I think I figured out why I feel so relaxed after a shave. The focus it takes to shave properly, mixed with the cool burn of a strong menthol aftershave must release endorphins.
Not unlike how you feel after a hot sauce burn.
Or am I just crazy?
