How lazy is normal?

[HMT]

My BP enjoys just staying in his hide(s) all the time unless he is hungry. However he is very curious about things near and in his cage, and will always come out to look at changes I make, and will often poke his head out of the hide if there is movement near his tank. For a while I thought maybe he was eternally hungry, but that behavior continued through his winter fasting time, when he was refusing food. If I took him out of the tank... he's off! Places to explore, things to see, and don't you dare try to put me back in that tank!
