I'm hoping that cooler temperatures are heading your way LHW. And I hope that your husband is doing okay. Sorry to hear about your friends. The S and R situation would be so uncomfortable and stressful moving forward. Letting go is likely the right answer, but I'm sure that it is difficult, considering that you were there for each other during such a difficult stretch in your life. That would be hard for anyone.
Slow and steady on the exercise. Us "elderly" folk can't be overdoing it. Did you really include yourself in the elderly category? I'm not having any of it!
