Wow, I can imagine that really made the lesson crystal clear for you at that moment! Do you have any discomfort touching metal objects like the Lotus shift knobs?I have a very rare allergy to the cold (cold-induced urticaria) I developed at age 13. I learned quickly I am fine in air that is 50°F, but water has to be nearly 80°F before I can safely swim for more than 10 minutes (anaphylactic response). It's not as bad now (age 40), but still there.
