@BigboiChungus I'm nowhere near that fat. I'm only 210. But I've talked to them about what it's like for them.
Some missed being able to get up and walk around and do things. Seeing the same 4 walls 24 hours a day can get pretty boring. But they usually have enough entertainment and food to keep them busy. It can even be painful to move around a bit because of sores and they get out of breath easy. But also they enjoy their immense size, playing with their fat and not having to worry about much.
