I’ve never been to a gym.
So I’ll die 5 years earlier than you. Send me some flowers at the funeral, will ya?
But I’d sign up for a swimming treadmill gym in a snap.
A good one costs about $25,000.
With $100 monthly fee, 12 hours a day, 4 slots per hour, it takes less than half a year to recuperate the device price.
There are of course a lot of other costs (rent, electricity, water, repair, staff, etc). But if you can get a volume discount on the device and flexible plans to get more people to join at lesser fee, it may look like an ATM after a year or so.
If you have a few million dollars in your mattress, leave a comment.
