He is never bothered by mosquitoes.
I’d love having him around on moving day.
In Kurt Busiek’s super hero book, Astro City, thinly disguised Superman expy The Samaritan has recurring dreams of flying. Of course, he can fly in real life, too, but in real life, he’s always flying someplace as fast as he can, to save someone’s life. It’s always a means to an end, and never an end itself.
In his dreams, he just flies.
He will always be able to blow out his birthday candles with one breath.
He can eat hot pizza without burning the roof of his mouth.
Amaaaazing belly flops.
He can fold his laundry in no time.
Even when he trips, he never falls over.
Oh, and if he knows the codes, he can operate the TV without a remote.
How would he trip? Wouldn’t he just destroy whatever his foot runs into? 
He’s not bothered by a stone in his shoe.
He can eat sugary snacks all day and not worry about cavities.
(although…could his diet affect his body in any way? I mean, Clark Kent eats…what happens to that food?)
His farts level city blocks?
He can check the mail box without getting up.
Remember that sexy 7th grade teacher you had? Well, Clark Kent remembers his sexy 7th grade teacher even more fondly than you do. And in more detail.
Knows where all the phone booths are.
he could cheat at cards.
Followed by really cold ice cream without getting a headache. And he can drink all the coffee he wants, not troubled by caffeine or having to pee from it.
Stubbing his toe on the furniture doesn’t bother him.
It probably bothers the furniture clear across the room, though. He either has custom design alien technology furniture, or a closet full of stupidly cheap ikea stuff he can put together in a second.
All three of 'em.
