Huff, puff - I'm trying. But this ol' bear doesn't GO like she used to. LOL!
Just do what you can, it's better than not moving at all.
I just looked at a fellow freepers about page. There was this thing about the lion and the gazelle. The gazelle goes to sleep knowing it has run faster than the lion or it won't live. The lion goes to sleep thinking it has to run faster than the slowest gazelle or it will starve. The morale is keep moving.
