Iam 67 years old and maintain a fairly good health. I maintain a garden, which is about 5,000 sq ft singlehandedly. I work in the garden for almost four hours every day, most of the time digging here and there with a pick-axe and spade. I sweat it out till I am fully exhausted. Inside the house, I do some yoga combined with some exercise and weight training. What I want to know is that after labouring in the garden to exhaustion level, is it necessary for me to do indoor exercise and yoga? Mani G Iyer, Kadayanallur, TN [email protected] Compliments on your fitness and good health! After working in the garden, if you are managing to do yoga and weight training, you are doing great. As long as the exercise is enjoyable and there are no pains and aches after the workouts, it is fine. In fact, yoga and strengthening exercises will help minimise potential injuries from the gardening work. Have yourself medically evaluated periodically to ascertain that all your health parameters are okay. If at any time you are not enjoying the exercises or feel fatigued, you could cut down the frequency and intensity of the exercises. My best wishes to you for a lifetime of fitness and good health.
