An Attempt to Stat Children

[noob]

If you gain RHD simply by aging, regardless of your class levels, and those can't be replaced, wouldn't it even out for all races? That child could start taking Wizard levels when he's young, but would still gain RHD as he ages.

So I guess I just have to gain enough wizard levels before I age to use that spells that makes you younger to stay a child forever(or even younger for having only one half rhd but then I will need to umd horseshoes(do not ask it makes sense for wizards)) and thus never have that awful ecl increase from ageing(I mean it makes every humanoid of the universe weaker against monsters except for some commoners).
Well I guess than now I can not remove from my mind the image of wizards who reach ultimate arcane power by becoming babies(the lower rhd compensate the fact you now have 3 int and the 3 int can be increased through wearing horseshoes and an ring of intelligence and one other intelligence increasing boost).
