I can't say for sure if you'll actually live longer by working out and exercising often but it will help with your heart health and blood circulation and improve your quality of life as you get older.
People who continue to stay active as they age have a better quality of life in their golden years.
But people who live an inactive lifestyle tend to have heart problems and need to be on oxygen and can't move out of their chair or bed.
I take a walk early in the morning before going to work and when I get home I take an evening walk.
I feel better when I exercise.
