Mack, you just said that you're really young at age 75. Can you describe how important continuing to work and be part of a community is in terms of continuing to feel young as we age?

Well, I think being part of community is really important whether it's work or not or maybe it's service work. Maybe you work at your church 40, 50 hours a week, maybe you work in the community 40 hours, 50 hours a week. You may not be being paid for it, but you're involved with a community.

Community brings life to people, you know, I see these kids all the time come out here. They're lost, never had a job, they've been in jail, they've been in trouble and all of a sudden, they become part of this community and 6 months later, they're feeling better about themselves.

A year from then, they bought a car, they've got an apartment, they've got some furniture, and they've got friends here, and it's about that community.

So I think there's unity in community, whether it's a work community or a faith community or a volunteer community. You got to be part of community cause’ community brings strength and assets, and encouragement, and being a community of one, that's the loneliest number.
