Happy New Year. 2011. This is the year the baby boomers (1946-1964) start turning 65. 65 in 2011 is not like 65 in 1981...first off, they don't like to be called "seniors" (they prefer "mature adults")...they are more active than their counterparts 30 years ago. They want to stay fit and healthy. They are going to gyms, getting personal trainers, taking exercise classes, yoga classes...and it all benefits them in the long run.
By the year 2030, there will be 70+ million people over the age of 65...with health care cost skyrocketing, an ounce of prevention, as the say, is worth a pound of cure. Starting an exercise program will increase flexibility (which will aid you in slip/falls), improve cardiovascular health, change your metabolism, add to your longevity, prevent certain ailments from occurring, lower your medical costs and improve your overall well being.
It's never too late to get started with an exercise program. It's just keeping up with it that's the hard thing. All you have to do is spare one hour a day. That's all. One hour. 7 hours a week. That's it.
