[X-Films] What would be Logan's natural lifespan with his regeneration with and without adamantium, assuming he didn't have his death sped up by the crazy circumstances of anti-mutant GMO corn and Xavier regularly harming him?

Basically, if he died of old age in both scenarios at otherwise "full" power, with and without adamantium. What kind of life spans are we talking?

TLDR: Around 584. Born in 1832, died in 2416.

In the comics, it is established that mutant healing factors can't keep up forever. Technically speaking, he could die at any age if he suffocated, or drowned. Healing factors only work on physical injuries, and when you drown/suffocate there is nothing to heal. You would just simply stop. But let's discount this.

We'd have to assume that his healing factor works by replacing his dying cells with ones that were similar to his healthy ones. Wolverine might look good for his age, but it's all the healing factor trying to keep up. And as you get older, your cells break down faster and become harder to repair so you produce less of them. That's why we get wrinkles, grey hair, and just slow down in general. This process begins some time in your mid twenties on a cellular level. It's the same for Wolverine. He does age, just way slower than we do because of the factor. Despite the healing factor, age will kill you eventually because your cells simply won't be able to keep up any more.

In the comic Wolverine: The End (2004) , he states his age as 210. If we subtract 25 as a baseline for cellular aging, we can say that Wolverine's body has been fighting the aging process for 134 years. He's also stated to have a biological age of 50 in comics from the same time. So comparing his biological age to his chronological age, we can calculate he ages roughly 1 biological year for every 7.5 chronological years. So if we do the sums on that (minus the 25 years we established for not fighting the aging process), and compare the result to the lifespan of the average healthy Canadian male (81.24 years), he'd live to around 584 before his healing factor can no longer keep up and he simply passes away due to old age. In the films he's said to be born in 1832, so he'd die sometime in 2416 based on these sums.

Arguably, this is the worst way to die. Seeing all your loved ones age and die around you while you keep going no matter what you try and do just sounds horrible. Plus, because it can't stop you truly aging, it's basically a power that's destined to fail. Healing factors are kind of a horrible thing when you look at it that way.
