That's kind of the idea. By the time they're 65, let's retire these farmers. Let's not keep them there until they die. If that's what it takes to make space to bring new farmers in, then maybe that's one way of doing it. It's a disincentive to keep going. Maybe it's time to let that farm roll over, and that might be one way of doing it.
