LOL, us old guys have been getting bombarded with tee vee commercials about how our T levels are dropping. One commercial shows the "gas guage" hitting E (as in empty) at 60 yrs old. I turn 57 next January and yes, I succumbed to the tee vee (and radio) pressure to take their pills and get my vigor back.
I can say that being at the starting line, doing a big burnout, and running down the track beating some hapless chebby is kinda thrilling.
Easier than riding dirt bikes in the hilly woods too.
