Yes being without power especially if you don't have a standby generator is bad in sweltering heat!
I remember when I was 13 we had a bad one and didn't have power for a week and could hear chainsaws in the distance for cleanup. All I wanted to do is work on it too. Later that year in fact I did, it was firewood heaven. Falling, limbing, bucking, splitting and stacking. 10+ cords for the heating season. Doing that keeps you young. Up to a point. Now if it's above 75 especially with humidity I only run a power saw if I have to. Winter won't come fast enough! There's nothing like splitting oak logs on the eve of Thanksgiving. Unless it's in the 60s.
