One of the chapters in my book recommends that even if you take a cart on the golf course, walk as much as you can. In fact, the USGA asks that you sign up for their "I'm a Walker" campaign. But walking is not only for the golf course.
Here in the US we walk for exercise. In Mexico and other countries, many people walk to get to places they want to go because they don't drive cars or take taxis. Yet being very interested in longevity and healthful living, I noticed something. Everyone walks, not only the young and fit, but the elderly as well. And I didn't see anyone on walkers or canes.
I live in an over 55 community where there are many people in their 80s and 90s. Many of them walk everyday. And it could be the chicken/egg thing, but I don't think so. Those who walk have great posture and stay healthier than those who don't.
My daugher-in-laws mother has high cholesterol from time to time. When she is in Mexico with my son, she walks all the time - everyday. When she visits her other daughter in San Diego she doesn't take daily walks. Cholesterol in Mexico is normal. Fresh from a trip to San Diego, off the chart.
I'm convinced walking is the fountain of youth. For me, a 45 minute walk on the beach everyday is invigorating. For you it may be a 10 minute walk around your block. Whichever you do, continue to do it. You may be surprised how good you feel after a few days.
