Natasha Romanoff (Marvel Comics) "AKA Black Widow" is said to be almost 70 years-old, yet she has the youthful appearance and vitality of a woman in the physical prime of her life because of the Red Room's super soldier serum.
Ability/Power:	To have an extended, yet non-superhuman lifespan compared to normal members of your species.

"Hey, Wild Bill, you still own this dump? Cole?! Good Lord, man. You STILL look like a punk kid!! Clean living, bud."

― Cole Cash and Wild Bill (Wildstorm/DC Comics)

"A General!? You liar!! How the hell can some little kid like you be a General?! You're quite rude to keep calling me a brat. Even if I look like this, I'm in my 30s, you know."

― Ri Shin and Rin Ko (Kingdom Vol.19)

The ability to age slower than normal members of your species, though not to the superhuman level. Sub-power of Peak Human Condition. Real world version of Decelerated Aging.

Also Called

• Exceptional Aging Process
• Peak Human Extended Lifespan
• Peak Human Vitality

Capabilities

Individuals with this ability are at the peak of human conditioning. For this very reason, they age slower than normal members of their species due to having extremely healthy cells, without the superhuman level. In addition, this power would activate when the user is in his/her young-adult years and they'd look twenty-years to even a hundred times younger. For example, in Captain America's state, even though he was frozen in the ice for nearly seventy-years, Steve still had the vitality and appearance of a man in his physical prime and completely cannot age.

If users that are enhanced were to "super-charge" this ability, then they would achieve the superhuman version of this ability (the user could gain immortality if the augmentation is powerful enough), meaning that users can live over thousands of years old without any signs of aging. Finally, for users that have not been enhanced could live up to 150-200 years since this ability is at peak-human level.

Limitations

• Enemies who can control the physical age or biological cells of others; therefore, becoming highly dangerous if the Peak-Human victim is originally elderly.
• When users become elderly, this ability will automatically deactivate.
