In some Japanese anime, games etc. people seem to age way more quickly. 14 - 17 is mature, and 30 means basically retired already.
Case in point... Sephiroth and Mario are about 25, so presumably Luigi is low 20s at most. Ash's mom from the Pokémon anime is under 30. Auron in FFX is like 30, same for older Noctis in FFXV, though they look mid 40s.
