Fully armoured, a Space Marine typically stands 2.1 meters (6'8") to 3.0 meters{{Fn|50}} (9’10") tall and weighs 500-1,000 kilograms (1,100-2,200lbs). Due to the nature of the zygotes that make up Astartes [[Gene-Seed]], all Space Marines are male.{{Fn|52}} Space Marines live far longer than average humans. [[Dante]], one of if not the oldest currently active known non-[[Dreadnought]] Space Marines, is over 1,100 years old.{{Fn|54}}A former [[High Marshal]] of [[Black Templars]], [[Ludoldus]], appears to have lived even longer while he was still alive, having served for over 2000 years.{{fn|16b}}{{fn|16c}} A member of the [[Salamanders]] from the days of the [[Great Crusade]], [[Gravius]], later became stranded in space and was not rediscovered for some 10,000 years. The Marine was still alive in an inactive state, though withered and frail to the point of warranting being given a merciful death upon rediscovery.{{Fn|57}} Some Space Marines may initially believe their memory to be eidetic, but even their most glorious memories as an Astartes might be forgotten over the centuries.{{Fn|69}}{{Fn|71}} This all lends to the theory that Space Marines while subject to gradual aging are "functionally immortal", though since they all inevitably die in battle one day there is not enough sufficient data to come to any firm conclusions.{{Fn|58}} Some Space Marines may initially believe their memory to be eidetic, but even their most glorious memories as an Astartes might be forgotten over the centuries.{{Fn|69}}{{Fn|71}}
