how old are you when you first watch anime

It is wild to look back how much I grew up with anime, I was 4 in 1999 and fell hard for Pokemon. That was the gateway drug to Sailor Moon, Digimon and Ghibli movies. My mom got me Kiki's Delivery Service from the library when I was 5 or 6, and it is still one of my favorite movies. Classic anime seems like such a naturalized part of 90s/00s childhoods and I am thankful for it!
