Well, now that you have all the money you could imagine, and all that spare time, you can look after yourself, train and get in better shape, become healthy … Does that mean, while you are still in the working hard phase, you should not do that?
We have only one single body – at least till Sheldon Cooper finds a way to transfer our minds into android (not the phone) bodies. Take care of yourself now! If you have not seen a doctor for years, make an appointment for a checkup immediately. If you have, repeat the checkup every year!
If you are still in a 9-to-5 job, do the same, don’t wait till you have the time! Don’t wait till you are rich and can effort your very own personal trainer.
… because most likely, when you became rich and have all that abundance of time, you will want to reward yourself and enjoy those twelve-course menus delivered directly to your pool where you sleep all day …
