That reminds me of learning to snow ski for the first.
A British woman friend of my Mom, in Como Italy, sells us her husband's snow skis.
I show Giorgio (Renato Molinari's brother) the skis at the Como shop. And he takes a hand file and starts sharpening the metal edges of the skis. Telling me this will help to cut into the ice better.
I go north of the shop, and take the ferry across lake Como, to a local ski slope. I still have the scar (it took stitches to close) from coming down one of the slopes. Turning, I slipped and one of the skis cut the inside of my leg below the knee. Heck I am from Florida, I have never played in the snow before. However, since then I am an intermediate level skier. I have been on black diamond runs (some sections very carefully & slow) at Mammoth, California.
Regarding going fast on a motorcycle, my criteria is do not exceed your braking skill level. I respect applying the brake bias (front & back brakes respectively) in a balance controlled descent. And again, another scar on one my hands (still there). Road is wet from rain, and I am on my cousin's bike, I apply the brakes and the rear goes sideways, and my hand is under the handlebar getting dragged on the pavement. No stitches they use butterfly bandages.
Like snow skiing, you get up, and get back on the bike. Both sports give you a sense of freedom & serenity. As does a fine day on the water too.
My mishaps, I am sure are minor compared to you guys dust-ups.
