I've had this fetish for as long as I can remember, and I wish it would go away. I don't think I will ever be able to find a significant other that would be willing to participate in my strange fantasies, but I accept that.
The lazy kids just walked the mile run and still passed. They barely, if at all, participated in valley ball, dodge ball, soccer etc. Like I said, a waste of time. But teaching teens how to stop an arterial bleed, perform CPR, patch up a wound etc. would not be a waste of time.
