I was trying to figure out how many generations could theoretically exist at the same time, so I decided to first check Guinness. Hopefully I did all the math correctly.

I think OP made an error in stating you had to be 18. The oldest living person ever was 122 (as indicated by Blamemeta). As long as you are allowed a few pre-18 births, you can get to 7 generations). At 15 years old you can get to 8 generations.
