Well, I say it's just good genes and nutrition.

However if he still looks like that 100 years from now, then we may need to have a conversation...

Never forget that Hollywood stars have access to the most expensive & exclusive skin care, trainers, health care, & even plastic surgery, the likes of which we grimy little Proudfeet will never even hear of. Check Cate B out too, she hasn’t aged an hour

Hasn't aged a day:

That isn't the effect it had on Gollum.

He feels thin, sort of stretched, like butter scraped over too much bread.

He's under 50, hardly a lad in Hobbit years.

I mean he was a kid when he was hired to play Frodo. He seems relatively young cause he still is

I had the biggest crush on him growing up. Stupid sexy hobbitses

Did y'all forget that Frodo went to the Undying Lands? He only visits for work.

Edit: it seems I've forgotten... he'd still age in the Undying Lands.

This confirms he is a Dark Lord then, and must have purposefully sought to infiltrate Valinor. I don't dare to guess his intentions...

He'll likely be restless by his 111th birthday.

Damn, he's 43, so I guess 39 in that image.

Yeh this feels a bit of a stretch for someone aging from early 20s to early 40s. A, some people have good genes. B, we tend to notice men’s aging with less weight(ymmv culturally). And, C he’s a millionaire movie star with access to the healthcare that comes with.

I'm very very slightly younger than him and aged the same way. My beard grew in better as I got older and I got a better haircut, but other than a few grey hairs in the beard, a couple of extra pounds, and a slightly changed hairline I'm really similar to the kid in the picture from my boot camp graduation. I expect that to change pretty hard in the next couple of years when all my drinking and hedonism finally catches up to me.

Did you ever hear the tragedy of Darth Plagueis the Wise?
