To survive in the 13th century you would need an endless supply of swords and be really good at braiding hair.
You would get bitch slapped like, every day, or have rocks thrown at your face even if people liked you. Because, apparently, if people like you they throw rocks at your face and they do the same thing if they hate you.
You would never be able to sleep because dudes would constantly be showing up on your turf trying to take your turf, or your woman, or burn your turf. Hence the need for previously mentioned endless supply of swords.
Everything you own would eventually be set on fire. Including your horses. And your woman.
I would hate living in the 13th century.
