For too long we have been led to believe that old and decline are inevitable. My advice is to change this mindset NOW! Of course, as we age there are some physical and psychological changes that take place but these can be helped with regular exercise and lifestyle changes. These are the only youth- giving benefits needed to take us into middle -age and beyond. So, please do something for your body every day.
It does not matter what type of exercise you do, provided you are active.What is important is to find an activity that challenges you and is fun.
