I was not going to say this, but what a heck, you keep me lunatic anyway
You know saying "If you can't win the enemy, join him", you know from movies where hero is undertaker and certainly going to loose, but instead running away he turns against to superior enemy, flying, driving, running and attacking like has lost his/her brains on that last hit.
Do you know how to get rid of nightmare, specially if it repeats every night? Don't run away, turn against and attack against what ever there is that is chasing or if there is place that you scare and it starts pulling you don't try to escape run into that place.
Now what the f***, that JTbo has lost his last braincell you are thinking, maybe, maybe, but all those above are examples of winning fear with adreanaline and this is what you need in reallife, you need to enough strong/braindamaged to go against fear, giving s*** about what to come, then you find that you still are not close to limit and start really enjoying from racing, some never go above that line...
In sim racing, you would need really good imagination to feel this, even with finest VR-helmets and motion simulators you still know that no matter what you do you will be ok, it does not come from your thinking part (sorry, don't know these in english) but from not thinking part of brain, that is what works and solves problems when you sleep etc. Really sorry, I miss totally english words from this area
It is quite interesting this human mind, but I should warn you, study it too much and you may get hooked
