I've always kept myself in good shape but as you approach your 70s you might look in the mirror and gradually realise you're maybe losing some of your physical appeal.
However that has never really affected the level of service I've received from SPs no matter what their age, and now that I'm an octogenarian great granddad, the ladies generally treat me better than ever.
Extra little details like setting up my jump leads, helping me turn over, getting dressed and tying my shoe laces etc.
I did used to worry about meeting my demise on the massage bench with Flossie sitting on my face, and tended to favour places like the Pink Peony in Liverpool, as it was opposite the A&E dept at The Royal Liverpool, but now I've realised there are far worse ways to depart this life.
