Assuming this is meant somewhat as a joke, but I would argue saddle hunters are more likely to fall into the 1/3-2/3 of the population that are not obese/overweight. Also would argue the average age of bowhunters vs all hunters is lower, although I am over the age of 40. Finally, I doubt the average saddle hunter doesn't know what he is doing. I am on year two of saddle hunting and year one of one-sticking & rappelling and can say I feel safer now hunting from a tree than any other year hunting from a ladder stand, hanging stand, etc. I assume like most on this forum, that's the result of spending hours learning about equipment, technique, and practicing before ever hunting from a saddle. I believe what you are describing is called an "outlier." There was a study that showed those riding a bicycle while wearing a helmet were less risk averse (rode faster, etc.) than those not wearing helmets. I think we have to be careful not to place too much confidence in our equipment. As
@slonstdy described, the equipment is only as safe as the individual using it. Like all sports there is a level of risk, and as the number of "exposures" increases (i.e., the sport grows) there are going to be more "outliers." (I could lose a couple pounds though.)
