text: why do people grow? its a weird question but why do people grow, why do they get older than their 30 years of age? like cant they stay at their 20's or 30's? why do we have to grow old and get wrinkled and weak? its just  a question that popped into my head just now we couldn't be born at a full grown size.  believe me mom wouldn't like that.  so although it doesn't feel that way to mom while she has baby in her womb, we all have to start out small.  2 cells to be exact. http://www.fwlc.homestead.com/fetaldevelopment.html here are some preborn baby facts & pictures.   http://pregnancy.about.com/od/fetus/  how and why we age. http://haldane.biol.ucl.ac.uk/age.html  why we grow large and then older   http://www.wiwi.uni-konstanz.de/fb/admin/paper/robson.pdf  well it all works this way.  gradually we loose some of our health and abilities.  if we didn't wear out we would never be ready for heaven.    god bless you in whatever stage of life you are in.
