One fix could be to just be to change skill points earned during character generation into stat points. However this opens a whole new can of worms that makes it cheaper to improve several skills at once as skills in TNE are heavily dependent on stats and in most cases makes up 30 to 90% of the asset.
Here is my fix.
1) Roll 1D10 above one tenth (drop fractions) of the age starting from when the actual aging is started for that race. Example: A human starts aging rolls at the age of 34. If the roll is three or less, the stat that is checked for aging are reduced with one. If the roll is below half of the required then the stat is reduced with 2. In this case the roll must be one.
2) In certain careers there is an requirement to stay fit. This includes any military career, law enforcement career, athletes. In these careers the player may roll again ONCE each term they fail one or more saving rolls. These careers are neither subject to the 2 point loss if the roll is too low. They loose only one point regardless of how much they failed with.
3) Everyone may trade in their hobby skill point for a saving roll, forfeiting a skill advancement to save against aging if a saving roll fails.
4) Characters of Vilani stock get automatically two or 1 extra roll to save if they are respectively pure blood or mixed blood Vilani. How to determine if your character are of Vilani stock is up to the Referee. Another hint is to consult the DGP publication MTA 1: Vilani & Vargr.
