i better start sabotaging my answers, i dont want a sorry ass
![whistle](/forums/images/graemlins/default/whistle.gif)
but i'll answer this question as follows:
when they (the lmb) are young, they have food
when they are older, they dont have enough food.
a couple (very small %) of the young ones figure out how to keep eating as they get older, and they turn into nice fish.
hows that?
