Rather late in the day...

I went blipping leaving DD chatting with her newly arrived friend, Colleen. Their 'chatting' is an activity that seems to consume no energy whatsoever and thus negate the need to consider eating to replenish stocks. Their jaws also seem to have a friction free interface avoiding any hint of ache and need to pause to recuperate.

Meanwhile your loyal Martian correspondent bemoaned his own energy sapping ways of peaceful reflection and quiet reading, and pausing only to shout, 'I'll meet you in the Frankfurter!', set out for much needed lubrication and belly filling.
