Ok well I have complied everyones guesses and it looks like this:
13yr -- 1 person
12.5yr -- 1 person
11.5yr -- 1 person
11yr ---- 1 person
10.5yr -- 2 people
10yr ---- 2 people
9.5yr --- 2 people
9yr ----- 3 people
8.5yr --- 6 people
8yr ----- 1 person
7.5yr --- 3 people
7yr ----- 1 person
6.5yr -- 2 people
6yr ---- 1 person
I was thinking 8yrs myself before I got the age back. Sufficed to say we are all wrong per the game department (or at least whatever lab they send it too). The answer is 🥁🥁🥁🥁!!!
