POSSESSIONS AND DECOR: The apartment comes furnished. It saves him from having to bother.
HOW TIDY ARE YOU? Very tidy. It's been a long while since he was actually in the military but he's kept the habits, and "married" life didn't do much to break him of them - Vision wasn't exactly one for clutter either. He'll pick things up and put them away without even consciously thinking about it. Occasionally he might leave a book out. Now that he has a dog, Minka may leave her toys around, but even still he'll often toss them back in the basket they're supposed to live in.
HABITS: He's pretty predictable a lot of the time, and tries to keep busy. He's usually got at least one project on the go, whether it's preparing for a particular medical procedure for someone, planning an upgrade of his own, maintaining the clinic's records, or just researching one of his long-term ongoing background topics of interest, and will often have his computer out while he catches up on the tv and movies he's missed. While he can cook he prefers not to if he's not feeding enough people and will often opt for either one of the healthier takeaway options or throwing together something incredibly simple.
SEXUAL HABITS: Unlikely. It's been a couple of years since Vision died but he hasn't really felt the urge to get back in the game - there's no one around that sparks his interest enough to date and he's not feeling the one night stand thing.
DRINKING: He drinks more now than he used to, but he tries not to get drunk at home - he's aware enough of his limits to maintain a buzz for quite a while. If he's going to go beyond that he'll go to a bar where it's not so obviously out of place.
BEDTIME: His sleep has gotten fairly intermittent lately. Sometimes he'll do an early to bed, early to rise sort of routine with a bedtime of about 10pm. Other times he'll sit up until 1-2am or get up during the night. He's almost always up before 7am though and starts the day with a run.
SHOWERING: The best part of civilisation is hot running water and the best time for it is in the morning after his run.
VISITORS: He's pretty chill about them most of the time. It's all good, stop by, as long as he's home he almost certainly won't mind. Very occasionally he'll be in the mood for quiet, but he's also normally decent at straight up saying so.
DEAL-BREAKERS: Messiness, especially unhygienic food messes and the like. Moving his things - they're organised and he knows exactly where everything is! Being particularly indiscreet about sex, not because he's a prude or anything, just coz it makes him remember that he can't have that anymore. Pushing his boundaries. Past some surface friendliness he can be quite a private person and will try to politely deflect or change the subject when people broach a level of emotional openness that he hasn't initiated himself. It bothers him when they don't take the hint and he will remember it, even when it seems like he's moved on.
