I will be 72 tomorrow, and I "used to be fit". I have arthritis in my feet (and almost every joint) so some days just doing one specific housework job (ironing/washing/mopping a floor) is as much as I can manage. I cook lunch from scratch (fresh vegetables/meat/fish) every day - lunch being our main meal. This latter because I was advised that the later one eats, the less likely it is that you will be active enough to burn off the calories ingested. Obviously this only works for those of us who are fully retired. I know I should walk more, but that means leaving my more disabled hubby by himself (he has a spinal nerve injury, wears a caliper and needs but cannot have two knee replacements). We have a pleasant and large garden, where I do "potter" sometimes. I am partially sighted, so if I did walk, I could not go far, as we live in a rural area with lots of ditches, no pavements, and lots of potholes! I used to swim, but I would need someone to drive (and collect) me to/from the nearest Leisure Centre (about four miles away), and accompany me to and from both the changing rooms and the pool. I'm not sure I would find my locker afterwards, either! Again, I would be leaving my hubby alone while I got my exercise. I've now persuaded myself that I should go out into the garden instead of answering emails and checking out facebook!
