I can do all the things the OP mentions, including digging gardens, having brown hair, painting the outside of the house. I am not overweight, wear jeans, drive long distances, wear trainers and spent the whole of Easter week on a boat on the Norfolk Broads, leaping on and off with mooring ropes and pulling the boat in at times.
Don't go for crocs or her taste in music and never did.
I, however, am 79, so the OP is nothing remarkable. I am quite happy for people to call me elderly, because I am. But being comfortable in my own skin, it doesn't bother me.
