Get an iPod, download awesome conservative/libertarian voices (might I recommend Armstrong and Getty out of KSTE in Sacramento, and they’re funny too), put on your sneakers and WALK. Move. Do *something*.
I have an 88 year old neighbor and she is always walking or working in her garden. She pays a teen age boy to mow her lawn but she even did that after her husband died. And she loves to laugh and be happy.
