What is prevalence data in relation to older adults and physical activity?

Simple fact,for the most part your physical ability slides lower as one ages.The study of geriatrics is a fast moving field.I think it boils down to the accumulated sounds over a life time that draws on ones health to the conclusion of life.That God spoke the world into creation and he takes us all out the same way.That should be some food for thought.Good luck with your inquiry.
