pushing to hard?

my hubby always says I am pushing to hard. He is not happy with me at the moment that I hurt my knee again, but really what can he do about it. It's what it is. I sat for along time reading and when I got up I didn't find my balance right away and twisted my knee. it's what it is.
When I feel fine I'll go walking and ride my bike. But I walk more now that it is Fall and so beautiful fresh and crisp outside in the mornings. I am staying safe where people are and walk in our neighbor hood, not because it's a bad place to live... It's because I often loose my balance and if I walk to far in the country I am always afraid I trip or fall and can't get home.

Anyway... even though I got a bum knee right now I LOST 1 lb! Yeah for me !!
