That would be Max from Mad Max. Hmmmmmmmmmm, a hardened survivor of a post apocalyptic world vs a soft out of shape bloke from Northampton.
There wouldn't be much of a fight, I think he would break every bone in my body before I even thought of throwing a punch. I could try to distract him by bringing up his dead wife and daughter in the hope of him having a grief flashback giving me the chance to kick him in the nuts and run while he is incapacitated. However, more realistically I think it would just make him more angry and he would break all the bones in my body twice.
