i'm new and loving this site

i'm new and i 'm glad I've found this site, i'm 63 and have a few aches and pains, which i'm hoping loosing weight will help. bad knees, which is almost a given with some one my age and weight. my husband (also large)will kind of copy what i do, so i'm hoping my change in eating will help us both. he has medical issues also but a different kind than i do. his is heart and sugar. mine is joints and muscles, i also has asthma. i don't expect this to be something that i can do overnight, I've been large for yrs. but at my age i would like to loose some,get healthier and see about getting some weight off my knees.any tips or hints to make this road easier would be appreciated, thanks,Wanda
