Peter (MCU) / Carol
"This coming from the guy still in high school?" Carol shook her head and winked at him. "But yeah...it's definitely weird. For a human, I mean. There are some species in the universe that live thousands of years. Maybe millions."
That question caused her to flinch. Not the grown-up part. The growing old part. "I...don't know. Kree live for hundreds of years. But my body regenerates rapidly and the cells heal themselves. As long as something doesn't blow me to bits, I don't know if I can really die..." It was something that plagued her. "That looks like it includes aging. But, who knows?"
