I spent ten days in Colorado visiting my son Peter and his family for the Xmas holidays. I'm now in my 76th year and still able to travel with ease and spend fun time with Lucy and Oliver my grand kids. Not that this is such a great accomplishment but so many of my contemporaries have a difficult time doing something as simple like traveling to see their families. I attribute my ability to enjoy traveling, including biking trips to Europe and South America, by staying fit through exercising every day and eating a healthy diet.
Keep it Simple. Consistent and Fun.
