If you only do it once or twice a year...yeah it might be a little tricky. But after you do it several times it gets really easy.
Old farts like you are always whining about how they can't do this and that anymore, and how they aren't as steady as they used to be ....blah blah blah ...Just get out there and do it, you'll figure out a way to get it done without busting yourself, and then you can quit worrying about how old and feeble you are.
If I don't go fishing for awhile I fall all over the boat. After a couple of trips out I'm as steady as I ever was. I used to climb poles for a living, but now I get scared when I stand on a chair to change a lightbulb. Give me some climbing gear, a stack of work orders, and in 3 days I could be running up those poles like Tarzan again. Guarantee it. 😊
You aren't old and feeble.... you're just rusty.
