Fat experiences

For the Butterball I think everything is more difficult. He's grown fatter still recently, and Sundays are days I see him doing housework. Everything is harder - he takes longer to get upstairs, and our washer and dryer are in a storage room in the kitchen, which now requires a little choreography on his part. I hear him getting breathless at times.
The tasks take longer, and he needs to rest in between. Also he feels the heat more than he used to.
During an obstacle course I made him go through, he had to touch his toes, which I now know is unthinkable. When he's weighed he can't see, I have to read the weight to him - when I choose to tell him.
He can't fit in his chair at the office, and the arms of the dining room chairs make him think a little more. Taking him on walks gets harder as he gets slower.
He's had to readjust his balance, and it's surprisingly easy to roll him over, assuming I stay in shape.

The little man has grown fat enough that stairs are now a problem. He seems to avoid them. Recently I noticed a new routine for him, and when I asked about it, he said the stairs were an issue, that he was too fat to walk up easily.
I've of course heard this problem before, but I hadn't realized how much it would affect him.
