While a healthy diet is a vital ingredient in feeling youthful there are other things of importance. I have just spent ten days up at the Edinburgh Fringe festival working as a volunteer for a company that manages a venue. I worked in the kitchen, the cafe, box office, and did cleaning and leafleting. Most of the other volunteers were young enough to be my grandchildren. I spent a lot of my time on my feet, did miles of walking and running up and down stairs. I also ate like a horse - and arrived home weighing slightly less than when I went! So not CRd for that time. (Back on the straight and narrow as sson as I got back) But the huge buzz I got from the vibrancy of the place and the massive engery and enthusiasm was like an injection of youth!
On another subject - I have a small garden, and while I suppose I could fill it with vegetables I choose not to. I do grow fresh herbs, but I can get organic veg from the local farmers' market. In my garden there are flower beds, a rockery, hanging baskets and containers. It is a garden to give peace and visual pleasure. I enjoy being there and just pottering around tending to it. I am sure the feeling of contentment I get from the garden and also the gentle exercise contribute to my longevity as well as my diet.
