hi, ygrec - well, first of all you need to stop smoking. even a few cigarettes a day do serious damage and you can develop COPD and emphysema. walking daily and light resistant weight training 2-3 days a week are recommended. the weight training is especially good for your bones! recently, i took up cycling and the low impact of it and cardio benefits are spectacular. also good for the bones are calcium with vitamin D vitamins.

dietary wise, you have to eat your leafy green vegetables daily. coffee and tea (watch out for the sugar) are both good for you with antioxidants and flavenoids.

i know someone who read novels everday to keep his mind sharp. and, it did until the end.

to protect your cardio system, you have to keep the arteries flexible. olive oil is great for that. pour EVOO on all foods as much as possible. other foods that help with that are oatmeal, beans, fish oil pills, cold water fish including salmon and tuna. olives are a great snack. it is also usually recommended that one lower salt intake. say 'bye to dessert cakes, pies and snacks and say hello to fresh fruit.

being social helps a lot too. have you tried www.meetup.com?
