Why Is Goku’s Age Confusing?
Several factors make tracking Goku’s age tricky:
1. Saiyan Aging vs. Human Aging
- Saiyans age slower after reaching adulthood (explaining why Goku looks young in DBZ).
- As a child, he grows like a human but with enhanced strength.
2. Time Skips Between Arcs
- The series has multiple time jumps (e.g., 3 years between the 21st and 22nd Tournaments).
3. Training Effects on Growth
- Intense martial arts training accelerates his physical maturity (explaining his muscular build at 15).
