#because why wait

*name-drops as much as possible in hopes that will make the difference* 

What they smell like: Sun-warmed stone; as long as he's not wet this is something that refuses to go away.

How they sleep: Deeply, but if anyone approaches with the intent of waking him up/pranking/ill intent/basically anything that gets them within an arm's reach, Luke instantly wakes up. This has always been a thing, and it's not until after (much later, in fact) he finds out about the Force that he wonders if it has to do with that. If he's alone, he tends to sleep on his stomach.

What music they enjoy: Jizz, Gliz, Tusken ululation (he heard it once, and while he wouldn't describe it as "pleasant" it stuck with him), and after he joins the Rebellion, Core Drive, Alderaani Three-Choir Symphonics and Corellian ballads (Han pretends he doesn't have them, Luke pretends he hasn't heard Han listen to them).

How much time they spend getting ready every morning: Barely any time, partly from a combination of old habits of sleeping as late as he could and still be up "in time" on the farm, and because he only aims for 'presentable', usually. And such things like indulgent water showers or baths are a novelty he only experiences after the destruction of the second Death Star (bathing in lakes and rivers doesn't count for this).

Their favorite thing to collect: After he joins the rebellion, holos with his chosen family and friends, rainstorm experiences (there's been many an exasperated look thrown his way for either walking out into a rainstorm or coming back from one, completely soaked). Ship models was something he wanted to collect when he was younger, but he didn't have many aside from the T-16 Skyhopper one. Han gives him the first new one a year and a half after the destruction of the Death Star, after seeing him eye one in a market. It gets lost on Hoth. Leia gives him the second new one on their birthday after the destruction of the second Death Star, and from then on he's gotten (or picked up) quite a few others.

Left or right-handed: Right, but after his right is chopped off and he gets a prosthetic, he trains himself to be at least somewhat-passable ambidextrous.

Religion (if any): Jedi, Tatooinian spiritual beliefs (which include such things like the dead being able to appear and give advice).

Favorite sport: To watch and participate in; racing!

Favorite touristy thing to do when traveling (museums, local food, sightseeing, etc): Simply wandering the streets of whatever given city he's in, people-watching and finding nice, scenic views to watch sunsets at.

Favorite kind of weather: Rainstorms. Sometimes with added lightning, but he prefers when it's just pouring rain. (If he's honest, though, Luke has to add "bone-dry, cloudless days" to that as well.)
