When you write about sandwiches you tend to eat a lot of sandwiches.
Which is okay, if it’s half-sandwiches, but you tend to eat whole sandwiches.

Which is okay, but only if you’re a person who expends a lot of calories.
And if you sit a lot, you’re still a lot, and you don’t expend a lot of calories.

And if you sit a lot, you aren’t flexible either, so it’s harder to move if you have to.
So you sit more and that means even physical play is not “get to” but “have to.”

So you sit more because of your mood and you spend time doing things that waste time.
Even though you’d rather be productive and solve world problems, you waste time.

Even though you’d like to cook more, you worry that you’ll just eat a lot of sandwiches.
