Fast Biker

I went out for a quiet walk this evening and a lovely evening it is then along the street came a group of cyclists. They seemed to be in a great hurry compared to all those other people that were out going for a peaceful evening stroll.
This got me thinking, why is it that some of us have the ability to just slooooow down and enjoy life while others are always going at a hundred miles an hour.

Who is right and who is wrong????
