Paul Rudd is 52 years old.
And no, he sure doesn't look like he's aged a day since he was in Clueless in 1995.
So what is his secret? Is it skincare? Is it clean eating and working out daily?
Is it superpowers from beyond this planet that us puny humans may never be able to comprehend?
Well, according to Mark Ruffalo, it might be.
On his Instagram, Ruffalo wished Rudd a happy birthday with a picture of Rudd wearing Thanos' gauntlet from Avengers: Infinity War.
People responded by also wishing Rudd a happy birthday.

In the new phase of the Marvel Cinematic Universe, Ant-Man is expected to become more important and hopefully all of the extra work won't wear on Paul Rudd's perfectly ageless self.
Happy 52nd Birthday, Paul Rudd!
