Left out of this discussion so far are the peculiar dangers associated with aging. Slower reflexes, poorer eyesight and hearing, cardiovascular compromises. They sort of creep up on us, then boom, can get you.

This was brought to my attention recently when I allowed myself to become dehydrated. In combo with a couple of other conditions of age, caused me to pass out while riding. Would not have happened maybe even 5 years ago.

No reason to stop touring for sure. Just reason to be more careful and more aware of your limitations.
