You also got to put in the fact that this is Oddworld. It is ten times bigger than earth. Plus we don't know how long an actual Oddworldian year really is. A year on Oddworld could be like two years on earth or more depending on how long Oddworld takes to orbit it's sun. If Oddworld takes say three earth years to revolve around it's sun then do the math and you will know how old Mudokins are at 40 years in humen years.
