I had a friend just like this when I was growing up and now that I am older I understand what eluded me back then. Most Adrenalin junkies are the same as drug addicts. Only difference is that it's a natural high, but just like regular Junkies they will do anything for a fix.
To make a long story short my friend had a huge motorcycle and he got his really beautiful girl friend also hooked on the Adrenalin rush. Just like the first couple in the video he would be out doing crazy stuff, like 170MPH+ on the highways, eluding police chases and doing all kinds of other crazy stuff with her. Always claiming how great the love making was after a life and death ride.
Then one day he had an accident at about 60mph. They both went flying off the bike. He got up with barely a scratch but she had road rash all over one side of her face. He visited the hospital for about a week to check on her. When the bandages finally came off after about 6 weeks, he looked at her and then officially left her about two weeks later. Soon afterwards he had another good looking girl on the bike. I always felt so sorry for that first girl, she was so badly scarred that she stayed home 24/7 until eventually her parents moved. Like any typical junky he did not give a crap, he just went on riding. We parted ways right after he left her. I realized just how shallow he was and that he really had no friends, only people to hang out with and tell his stories to.
