The Beverly Center (seniors home) in Lake Midnapore is always looking for volunteers willing to work with seniors. I did this for 5 years and found it quite rewarding. You can help with the daily activities they have planned for the seniors like bingo and other things. Then there's the bus outiings they take them on. You can also volunteer for one on one visitations where you become a friend to those who have no family. I visited with a blind woman 3 times a week before she passed away.
Hope that helps
