Now that I think about that that is kind of weird I've been really into anime for 16 years, I was 12 when I got an animerica subscription, I'm 28 next month so that's more than half my life.
I've been watching for 1.5 years and I have already watched more than you have (according to your sig which I believe is dynamic). There is nothing weird about it.
...so you've watched at least four hours of anime every day for the past 18 months?
Huh.
...how do people find the time?
Actually, I watch a LOT more than 4 hours a day usually. Yesterday I put in a shabby 5 or so as I was cleaning n organizing my art studio, just recently started transforming my apartment into a studio and gettin' it sorta 'finished up'. Today I've watched almost 2 hours worth but again been working a bit cleaning neurotically and I watch a lot more late-night.
I find the time by not working(I'm nigh-on disabled) and not sleeping much. I sometimes watch whole series in one go, as in 12/13 episodes back-to-back. I'm probably gonna kill the Gunbuster OVA series today. I killed Madoka Magica in one shot with no real break other than to use the restroom; started at like 1AM, finished at like 7AM. I killed the first 6 episodes of Panty and Stocking in a few hours. It's easy to justify in my mind as I'm an aspiring artist and so I think of it as 'studying' or 'research lol.
I usually watch like 4-6 episodes of an anime in a row if not the entire series and I try to watch 2 or 3 different series a day as in 4 episodes each of 2-3 different shows. That means 4-6+ hours per day, sometimes just work through one series and a movie or watch multiple movies in one day but still end up over the 4 hour mark. I guess I rambled on lol but I'd like to point out I'm not fat or even getting there... 130lbs at 6'2" and athletic albeit wiry built. o.O Lovin' them genes lol
EDIT: my bad, made it sound like 6 hours is a 'lot more' than 4... When I've gotten a lot done in a week and feel like I can slack off, I put in like 9+ hours watching anime sometimes. Just wake up, get coffee, fire up an anime, shower after a while n put on more anime, eat, anime, check my torrents and clean something, anime, look at artbooks/shop online while watching anime on another screen, before I know it it's 9PM. Eat dinner and watch more anime till 3 or 4AM.
