Unfucking real. You know how you or your dad or somebody you know is a CPA and does accounting for a living? You know how you or that person are real good at accounting because that's how you or that person get money to eat and buy stuff?
Or maybe you should think about your mechanic. You know how he's real good at fixing your car because that's what he does for a living?
Or maybe the guy who built your house. Notice how he got paid money to build your house and it hasn't fallen down? That's cause that's what he does for a living.
See, Pulver fights for a living. That's how he feeds himself and gets money to buy stuff. That's his job, that's what he does. No hobbiest or semi-pro with a decent record is gonna kick his ass.
I would not advise letting Jens do your taxes or represent you in a court of law or performe surgery on you or even build your house, but if you need a top level professional fighter for some reason, give him a call.
