This is a great thread, thanks @Kanfuzed123 !!!
My DH - bless his heart - also exhibits some of these rather irritating traits.
On the very rare occasion he washes up, he takes about an hour and a half. I don't have a clue why, as I only take 20 minutes. He also spends sooooooooo long looking around stuff when we're food shopping, and peers at SO many items, looking at the fat and calorie content etc... I don't like food shopping with him and tend to do it alone most of the time.
Also, as pps have said, he is useless with dates on the food, and will grab a yogurt out of the fridge without looking at the date, so older ones get left behind! I have to stack them in the fridge with the older dates at the front, so he doesn't grab the newer ones first, coz he CBA to look for he date to make sure he gets an older one!
As pps have said, I reckon men do this shit so we will get sick and tired of it and do it ourselves!
He also has this thing about constantly covering his hands with hand gel too (the sort you couldn't get hold of in 2020!) and he even does it after handling a letter that the postman has shoved through the letterbox. And when he gets a package he 'quarantines' it for a week before opening it. 
He says 'I am obsessed with cleanliness, I have no intention of getting covid yada yada.' Yet he doesn't seem to extend this 'cleanliness obsession' into the home. 
He claims he is super neat and hygienic, but never EVER cleans the hob, the oven, the microwave, the fridge, the kitchen floor, the loo, the bathroom floor, the kitchen worktops, the sinks, the taps, OR behind the furniture. So it's definitely 'selective' cleanliness and hygiene.
And don't even get me STARTED on how he can't organise anything/book any appointments etc. it's always me who books appointments for dental, GP, hospital, opticians, nurse, and visits to our DC (and their visits to us.) I dread to think how he would cope if I left or died.
I have had times when I have been out of sorts for 4 or 5 days (tummy bug/flu etc,) and whilst he manages to feed himself (sandwiches/toast/pot noodle etc,) and feed the cat; absolutely NOTHING else is done. No dusting, polishing, hoovering, food shopping, washing, filing, life admin, tidying up, NOTHING.
I am probably not doing him - OR myself any good by doing everything, but after almost 40 years together, it's too late to change things now. I know some will say it's not, but it is. He is almost 60, and will never change his ways.
Oh and yes to the 20 minutes having a shit! And an HOUR when he goes for a shower, and to wash his hair. I take 15 minutes (when I wash my hair!)
