Deadpool is effectively immortal, although he has died several times. He is still alive 800 years in the future when the new X-Force encounters him. In addition, Thanos once declared that Deadpool should "consider yourself cursed ... with life!"
Deadpool's immortality only extends to his ability to regenerate from almost any injury. However, this doesn't mean he's immune to everything. He can still feel pain, he can still be incapacitated, and he can still suffer from mental and emotional trauma.
Obviously, neither are truly immortal in the sense they cannot die at all as The Death of Wolverine has shown. Deadpool was once “cursed” with immortality by Thanos but that was removed and, though still hard to kill, he can actually be killed. They do both definitely have greatly expanded lifespans regardless, though…
Deadpool survived various explosions throughout his time in the comics. Though they injure him or even kill him, his healing factor regenerates him, allowing Deadpool to recover from the blast. This is true even in the case of nuclear explosions.
Their Healing Factors make them practically immortal. Deadpool has grown entire limbs out of scratch. He has survived point blank explosions and a hail of bullets that turned his body into swiss cheese. Wolverine has survived being thrown from great heights and his flesh being stripped to his bones.
Deadpool's Face & Skin Don't Heal Because Of His Cancer
Many of Marvel's mutants undergo intense physical transformations when their abilities begin to emerge, though few require as brutal of a stimulus as Deadpool.
He does somewhat age, and his healing factor slows down with time, but it's unclear if he'd ever get to a point where he's dying of old age. That being said, Deadpool's aging, pain, and immortality are all somewhat inconsistent and vary from writer to writer.
He can't Starve to death. In one comic he was stuck under a fallen building (that's what I think it was), and he stayed alive in there for a long time. It was an alternate future scenario. Decapitate him and seal his head in a strong box.
Deadpool survived the Infinity War snap because he wasn't technically in the Marvel Cinematic Universe at the time.
Deadpool is a mutant who has an accelerated healing factor. He can re-grow his parts or attach them if cut from his body. He is said to have cancer, which resulted in a deformed face, but he does not die due to his heavy healing factor.
The speed at which Deadpool heals varies depending on the severity of his injuries, but generally, he is able to regenerate from most injuries within seconds or minutes. For example, he has been shown to regenerate from decapitation or being blown apart by explosives within minutes.
Deadpool cannot be killed no matter what you do to him. He was once turned into ashes by Thor and still managed to regenerate back. If his head is chopped off he can either wait long enough(very very long) to grow another head or could just buy some chimichanga and walk up towards his head.
However, Deadpool's healing factor goes a fair bit beyond Wolverine's, in that Deadpool's healing factor essentially prevents him from dying unless it is something catastrophic. Typically speaking, if Wolverine had an arm chopped off, he would not re-grow a new arm. Deadpool's powers do, in fact, do that.
Deadpool's regenerative abilities make him near immune to most toxins, but he can still feel some of their effects. Much like Wolverine, it takes quite a few drinks to get him drunk, but it's not impossible.
Unlike Wolverine, whose wounds sometimes cause excruciating pain as they heal depending on the severity, Deadpool has some degree of pain insensitivity. Deadpool is effectively immortal, although he has died several times. He is still alive 800 years in the future when the new X-Force encounters him.
Deadpool is easily one of the most powerful characters Marvel has. The fast-talking gunman seems almost fearless on the battlefield, but in reality, there's a lot that scares the Merc with the Mouth. There are two things though, that scare him above all: cows and clowns are a Deadpool weakness.
Moreover, the fact that Wolverine has defeated Deadpool in comics, as well as movies, gives us a clear insight into how the fight between the two will go.
Months later, T-Ray, now an agent of Thanos resurrects Deadpool, who has been killed in a fight with Weapon X, using an artifact Thanos gave him to create many copies of Deadpool. Thanos is jealous of Deadpool's relationship with Death and T-Ray is to "curse him with immortality" so that he may never see Death again.

Another interesting side-effect of Deadpool's healing factor is his superhuman ability to never get tired. His muscular system produces far fewer fatigue toxins than a normal human being, so he can exert himself at peak capacity for several days before he begins succumbing to fatigue.
Deadpool is theoratically immortal due to his healing(Thanos' curse got lifted), but due to how he acts, this only works against him. He's not one of “the most invincible characters", he's one of the easiest to defeat….. And that's ok, because that's in-character.
Depends on the marvel version. However, if Deadpool was completely regenerative and immortal, his left side will heal. This is because his heart is on his left side and it pumps blood. Else, on the other half, he won't live at all due to 0 blood flow.
Strong language is permissible within a 12A but the frequency of use in Deadpool puts it firmly at 15.
It appears that few wolverines live longer than 5 to 7 years in the wild. Some, however, do survive to 12 or 13 years of age.
