He!!, that's nothing. LOL During the summer just walking to my car exhausts me too. Only to get in to the car, which the interior temp is easily over 120 degrees, and due to even more heat my vision gets blurry. I go out in the a.m. and/or evenings after the sun goes down. I try not to go anywhere during the heat of the day.

Do what you can to keep cool. Hope your UTI starts getting better soon.
