No, it's been that long since I've rebirthed that character.
When you rebirth them, it sets their level and age back.
Most people try to rebirth fairly frequently.. Because Mabinogi is more skill-based than level based, and your ranks in skills carry over when you rebirth.
You get one ability point (To raise skills) everytime you level. It takes more and more exp each level, so if you can reset your level, you can go back to getting Ability points very easily!
