I think it's really bigger than that. I'm hooked myself scrolling reels, but I go to the pub after work and see retired or 50-70 year old men (barely know how to work a phone) scrolling through them as well. That's when you know they're addicting as anything. Can't go anywhere nowadays in public without hearing someone scrolling through reels who don't know how to behave themselves in public by turning down the volume or wearing earphones.
