Well. I don't know.
I'd think I would have a nice chance of surviving alone. I'm an athletic 25 year old man who does parcour, and also used to do gymnastics till the age of 17.
Physically, I would be able to outrun anything and everybody. Here in belgium there are not so many guns so I think I would have a huge edge going solo.
On the other hand, I'm not the type of person to go alone. Even if i'm capable of doing so, I'd like some company in one form or the other. So I suppose, if I would be in a group, I would be the guy fetching/searching supplies.
COULD I go lone wolf? Definatly.
Do I choose to do so? Probly not. I'm a kind and helpfull person. That could perhaps be biting me in the ass in one way or the other. But on the other hand, I'm sure people would love a nice and agile young man in their group.
Other skills I have would be Carpentry and Brickworking (that even a word? You know. Build houses and such). i know basic farming (grandparents used to own a farm and cattle).
My negative traits would be, that I have slightly reduced hearing (not by much) in my right ear, and I am rather shy.
if I would go in a group, I'd rather have it NOT more then 10 people.
