I hear that.
There is nothing good about getting older.
Guys like us that "fix shit"... it is a part of our identity.
Last year, I had a small leak around an old oven vent that went through the roof. I took out the vent and just patched over it... problem solved. Buuut... when I was coming off the roof, that moment as you swing over your ladder where one foot is still on the roof and one foot is on the ladder - I lost my balance and barely caught myself before falling. It was close. I don't have the balance I did before, my reflexes are slower, my knees aren't great either. That was a bad day psychologically.
I miss those days in my 30s. I looked forward to projects.
Not anymore.
