My husband has so many health problems—diabetis, liver cirosis, dementia, poor mobility, and on and on. I am 69, his caregiverand in reasonably good health. Right now we live in our own home, one level living and doable with the help of home health care 2 times a week. I realize that within a few years we will need to move some place where yard and house maintainance are not an issue. I dont know if we should look for a townhome, retirement community, assisted living or what? Should we buy or should we rent?
