Hello Mark and welcome from me,
Late 50s is cool just means you fit in well to the auld gits club. It gives you freedom to complain about having to use reading glasses, hearing aids and a multitude of other devices and pharmaceuticals.
The advice in the previous posts is good, just enjoy and ask for help if in a fix and it will be given.
Cheers,
Vic (shaky hands, hearing aids, pacemaker, poor sight - thank heavens for alcohol)
