Retirement means getting up every morning doing the things you enjoy doing, if that happens to be work then great that one can do something they like and get paid for doing it, which I have been fortunate to do most of my working life.
Now at 68 and still full of energy to engage in hobby things like, cycling, kite flying, walking on the beach 1/2 mile away.
If you treat retirement correctly you won't have enough time in each day to do all the things you like doing.
