Your the best customer and you've got your first endorsement letter in your knee. Just sign it RK, NC. When I ran the drill through my finger and peeled the nail off, my wife was on the phone talking with her dad in Mexico (lots of health problems), so I just went to the john, got out the finger bandages, poured some peroxide on it, and went back to work. My wife didn't even know for two days!
Yeah, that's a give-away alright. Add a small safety kit to the design - the Wheelchair Associations will endorse and St John's Ambulance. You could even have St. John's Ambulance put it in their newsletters.
Hearts always win over bleeding knees. So now you've got the knees that please! Tough way to get the trophy!
When I get it running, I'll get my wife to take a pic, in my boxers. Scars and all. But I don't recall wearing shorts...
