Conan the barbarian at thirty years of age has a strenght of 19. He almost never wear armor of any type, but could he wear an armor while swimming (say, a chainmail or plate mail) for at least some rounds before drowning?
Is it nigh impossible to perform this for a character with such a strenght? Keep in mind that it is likely that, in the age where Conan lived , his strenght was unparalleled and no man on the surface of earth could win him in battle- but at the same time wearing an armor while swimming is a tremendously difficult task.
Could he have done that?
