We bought a nice home 51 years ago and moved in with out family and a cat. It is a tri-level with eight steps up to the bedrooms and down 8 to the family room and garage from the main level. So life has had it's ups and downs ever since until today it's just me...and a cat! The stairs are harrder and harder although I have two knee replacements but to be fair the years are more and more for me too. On my birthday in a couple of months I will be 88 so I'd vote for on the main floor for the sewing room. But stairs are good exercise and I still love my home and especially my big yard.
