My darling is 96, can’t see very well, and has difficulty walking. Mentally he is pretty sharp but he lacks stimulation and activity. Therefore, he sleeps about 6-7 hours a day, plus a 10 -12 hours nite. Not much of a life when you think! Myself...87, no serious health problems except back and trouble walking. I am the sole caregiver for my husband and we wind up sleeping a lot and watching a lot of TV. Not the ideal situation and we know our life style is not healthy. How can we improve somehow our quality of life. Please help!
