People who keep a lot of tabs open, why?

When I say a lot, I mean A LOT. People who keep like 15, 30, even 50 tabs open on their PC, why? I keep wondering about it but I can't just figure out why, what's the benefit? Bookmarks exist, YouTube has a Watch Later list, so what makes the increase power usage worth it?

For me it's mostly just laziness. Like i sometimes feel too tired to close them. And/or is search multiple posts at once without going back to the main page over and over again.

I'm forgetful and having things open rather than bookmarking makes it easier to remember. Also just 5 of them are communication platforms anyways(whatsapp, spacehey, FR, FR groups)

I keep 4 tabs open, uni site, discord, and friendrewind, then the 4th is for any searching, playing, browsing etc. sometimes if need to have 5+ tabs at the same time if I’m studying or doing something super duper important but i will NEVER get the 14 tabs open thing, there is just nooo reason for that

I'm afraid that if I close my tabs, I'll lose whatever article I was reading forever...

I usually keep a lot of tabs open if I’m doing work or multitasking since I got 4-5 websites open as I’m doing work 

I might need them later idk

I forgot to hit the OneTab button.
