Hope is resilience in the face of sometimes-inconvenient facts.
Requisite
I’m watching a mattress commercial, and it occurs to me that there is such a profession as mattress designer, or mattress engineer, and I want to take one aside and ask them if there is really a design reason to make mattresses that thick and if so, what it is.
I’m not going to say this is a question which keeps me awake at night, but since this IS night and I’m still awake, this question does not exactly promote sleep, either.
