I am 60 also, but don't have the herniated disc. A second alternative is to put the Y-board in, and use a regular ladder instead of the steps I showed, 1 piece so it can't be stolen, spray paint it and lock it it with an industrial strength lock. I am thinking of doing that. Just some ideas to keep you huntin'. Also buy yourself a Gorilla seat,
