Oh that. Yes, I calculated with only 40 traits for teens, which was rather arbitrary, and rounded to 100,000. With 63 traits, the calculation would yield 595,665 possible combinations for teens. If you add in the traits from packs, you get 3,764,376 combinations for teens and 71,523,144 combinations for adults.
Of course adults can have more traits than that...
Edit: :lol: With 7 traits, like most of my family members get, the number is 1.4887031544e+10
Conclusion: Many guesses of the human brain are the result of really bad math.
