Hmm, back when I was 10yo I started karting, it was fun but I didn't take it any serious, adding to that I was sorta large. Not obese, but not as skinny as you need to be to potentially get to the sharp end.
The years went by, and after some good results when I was 13, together with stuff that happens in that age, I got more serious with my racing, started hard workouts over the winter, getting in pretty good shape, better than I've ever been. Went up to the Formula Yamaha class (some UK-guys might know about that class) and had instant results. Suddenly, for some reason I was actually battling on the sharp end here in my home country. Topping it all with a 2nd in the "Junior(U17) Festival" in Norway.
And that's where it ended, riding my bike to school the day after that race I crashed on my cycle in an underpass. Of course, helmets are for weak people, so I got it hard. Ended up with a broken skull, and pretty severe brain hemorrhage, and woke up in the hospital with Aphasia (couldn't speak, I could think the words and it felt like I said them, but just a constant "nnnnn" sound came).
After somewhere between 4 and 6 months with total ban on physical activity (other than walking and very slow cycling) and getting my talking somewhat back to normal - will never be OK. I was strongly advised to not do Motorsport anymore, due to the danger of brain injuries, like a concussion, and that my brain would not recover from another hit.
I did get back to karting, but with so many months with a total ban on physical activity I was not in shape anymore, and to get it to work properly, everything must be in order, but my Dad was pretty scared by the doctors words, so things never got back to any serious stuff after that. I did some RX-events when I turned 16, got into an A-final and some stuff, but stopped when I moved from home.
So ye, that's why I do enjoy simracing. It is a way for me to do the things I was "robbed" from due to not using helmet when cycling to school. It is also a good training tool, and while I don't care about setups and such (I always run default), there are much good theory to get to practice and learn from.
I made a micro-comeback in RX last autumn. Loaned a car from a fellow RD-member, got a couple of heat victories, and a C-Final even though I had to skip one qualifying heat. The fact that I hadn't been behind the wheel of a car, road-going or racing for over 8 years showed me that simracing does indeed work to learn the basics. I would never been able to do what I did last year without simracing.
Sorry for making it a "life-story" but it is all down to why I enjoy simracing
