I would just comment that the mandate of the Canadian Centre for Activity and Aging is to investigate the interrelationship between physical activity and aging. Most of the work, certainly with various programs, if a study is done, also looks at the mental health benefits.
I can say clearly, from the various older people who benefit from our programs and services, that the people who stick to the program long term are people who have made a variety of friendships and social relationships with other older people who have similar interests, similar challenges.
So the social component is very important, but I was speaking today specifically on the functional benefits of physical activity for veterans.
