You might wonder what is my interest here, since I live in the Tropics. However, I happen to know a lot about some similar "states" of immobility that tortoises can get into, like for example:. Hesitate - a temporary but perhaps alarmingly lengthy stop. Then you have Meditate - which is like Hesitate but with some element of deep thought connected to it. And of course also, your tortoise may sometimes Gravitate. This may be a bit disturbing to you, when you thought he was in one place but then saw him somewhere else entirely. But if you ever see him Levitate...then that is when you will know that both you and your tortoise have achieved a new and exciting level of existence!
