All the movie stars, famous musicians, politicians and renowned scientists, yes, those are all regular guys too. They eat, shit and fall asleep on a pillow every night or about as much as regular people do and usually not all at once. 2 arms 2 legs 1 head and so. Mostly. A bit above average perhaps, but generally they have a regular number of limbs.
Mark likely does all those regular things just as well as regular guys.
However… Someone who goes on a live stream to introduce his new cutting edge technology by staring into a camera without blinking for 45 minutes endlessly mumbling about smoked meats while rocking a caesarian haircut. That’s also perfectly regular… for a lizard.
