I am an old guy. I will be 80 years old in a few months. One thing you do not wish to do when you get old is to be a burden on others. That includes your family too. For that reason, you try to continue to do all the things you have always done for yourself. A case in point would be staining our back deck.
I just finished staining the back deck. I used to be able to do the railing and floor of the deck in one day. Not anymore. These days it is one day cleaning and taping it off. One day to do the railings and one day to do the floor.
The good news is I can still do it. It takes me quite a bit longer, but I can still do what it takes to stain the whole thing. I am grateful for good enough health at my age to still do things like this.
