1-He had to be synergized with the MCU (for some stupid reason).

2-All that time dealing with Ultron.

3-His daughter is almost an adult.

Wait so are they retconning that he's been middle aged all these years? Or something else

He was divorced before he met Jan.(Actually widower) Then he went through all those identities, crisis, mental breakdowns, and you are surprised?

Ok. So they aged him a tad up so Nadia's age could make more sense to make him closer to 40 but they went crazy with it for mcu synergy and made him like 60 I'm guessing

I'm glad Hank is back but why make him old tho

He just didn't age well? 45 but looks 60?

I don't think he's a handful of years older than Reed...

He was old enough to have 2 doctorates before he met Jan and founded the Avengers.

I guess....Sliding timelines are weird

But it kinda makes his and janet's relationship weird
