I have to completely disagree here. NASCAR is arguably one of the most grueling sporting activities, requiring excellent physical conditioning. Consider first, the fact that NASCAR cockpits reach temperatures of over 115 degrees farenheit and those temperatures are sustained, at times, for hours on end, and drivers commonly lose 10-15 lbs, if not more, of water weight per race. Consider then, that there are no cooloing elements within the vehicles themselves and that drivers, wearing sweltering fire suits must maintain focus for extended periods of time in what amounts to a sauna that moves at 200 mph. Further, drivers must be able to tolerate the G forces that come with turning the vehicles at high speeds under the same conditions which can easily result in a significant loss of vision and disorientation if a driver is not physically fit. Couple those concepts with the fact that controlling a 3,400 lb car, especially at those speeds, requires physical strength for both braking and shifting as well as significant forearm/wrist strength to maintain course and line at top speeds with steering wheels that take ample amounts of coercion to control given all of the other circumstances (G force, speed, other drivers feet or even inches away). Also, the cars are built aeordynamically, and at 200 mph with most of the air being forced away from the car , drivers have a significantly less amount of oxygen available to them inside the cockpit, which is obviously not pressurized like that of jets or other aircraft that travel at similar speeds, necessitating a very strong respiratory system and a workout regimen that, among other things is tailored towards maximum bodily usage of minimal amounts of oxygen alongside the concept that there is no ventilation on a NASCAR, meaning that large amounts of engine-expelled CO2 is being pushed directly into the vehicle which can cause dizziness and general disorientation, necessitating an even greater amount of foucs and concentration to even maintain conciousness and an ability to expertly maneuver a speeding vehicle, not only around the track, but in and out of traffic. NASCAR is indeed a physical sporting activity and anyone who disagrees, IMO, isn't at all informed as to the very real justifications of that statement.
On topic, though, I would really love to be the best pitcher in the world, or maybe even the best golfer. Both would be equally cool, IMO.
