Perhaps thymus is related to children high energy levels?
Other thing is, that children do not have GnRH and related hormones in their blood. As brain (hypothalamus) where it is normally produced is blocking its production.
as a side effect adrenal gland is stimulated by GnRH too.
Perhaps adrenaline levels are high in adults and thus adults are somehow less sensitive to adrenaline?
At puberty children have extra energy. Perhaps raised adrenal levels?
Actually, according to this (http://en.wikipedia.org/wiki/Thymus) the thymus continues to grow until puberty and then begins to atrophy.
Birth: about 15 grams;
puberty: about 35 grams;
twenty-five years: 25 grams;
sixty years: less than 15 grams.
It doesn't suddenly disappear at puberty, so I doubt it's having this effect.
