I do not have a girlfriend, Rok.
Anyways, thanks, that link helped me a little, although Team17's worms are no real earthworms (they have eyes, hands and a mouth)
But it is said, that Worms live ~6.5 years.
The average human lives 70 years.
Since Team17's Worms are something between human and earthworms (they even speak our language), i am pretty sure, that i can refer to both forms of life.
let's assume, that Team17's Worms reach the age of 7, that would mean, that a 2 year old worm already used 28.5% of its lifetime.
A human that already lived for 28.5% of its lifetime is nearly 20 years old.
Mmh. This would mean, that a worm at the age of 5 is like a human at the age of 50.
But although I say "Hello young Sir" to 50 year-old guys, i do not personally think that they are "young".. But Boggy B IS YOUNG!!
AAh, this doesn't make any sense.
/EDIT: GOT IT! It's quite obvious and I ask myself why I didnt know the solution way earlier.
Team17's Worms can reach an age of 17 years! Sounds logical, huh?
This would mean, Boggy B was in human-age about 8 years old when his father left him. And oh my gawd, it's f@#!ing sad if the parents leave their 8 year old kid .. forever..
BUT an 8 year old kid CAN handle this situation with the right spirit filled with VENGEANCE for his fallen father!!
Mistery solved.
8 years when his father left and about 21 years when he finished his training and entered the warfare.
an 8 year old kid is about half the size of a grown up.. Boggy B got six times as tall in those 3 years, but that doesnt matter to me anymore, worms grow in a different way as humen and i assume that a 5 year old worm is ALMOST grown up, it can get up to 3.5 inch instead of those 3 inch. (3.5 is the half of 7 and numbers always have any relation to 17)
That sounds ok to me, I thank you all for your help!
