When I was a lad, first time riding a bike with handlebar brakes, I made intimate contact with the gooseneck of a 10-speed… as it made intimate contact with a brick wall, decelerating suddenly from 30 mph to approximately… ohhhh… I’d say… ZERO.
But I can’t tell you much about the pain. I was somewhere else for about four hours. That period of time is missing completely from my memory. I only remember waking up momentarily in the back seat of a stranger’s car, to be driven to the hospital. The pain emanating from my groin was so intense that it fogged my mind completely, and seemed to radiate out of my body and fill the car… and then I passed out again.
I awoke later that day at home, to the sound of the Mr. Rogers Neighborhood theme. But it was not a beautiful day in my neighborhood. Apparently I had been “out of it” the entire time, from the hospital exam to the trip home, to an hour or so nap on the couch. But the pain had mostly gone except for a dull ache like a sore muscle or bruise.
The only injury on my body was a small rupture thru the skin of some blood vessels and fatty material… apparently my right nut had been driven into my abdomen with such force as to cause my subcutaneous fat to erupt thru my skin.
Fortunately, something down there is working, cause 30 years later I’m about to be the proud papa of a baby son in, ohhh… about two months now…
