I firmly believe that everyone should bike. The world would be a much better place to live in if we all biked. People would be healthier, because they'd exercise more. They would feel better about themselves since they'd be in better health. And since they'd feel better, they'd be happier and would treat others better. Then, everyone would start being more friendly. The world might actually become a great place to live in. There would also be less pollution because we would rely less on cars. There'd be less traffic too, which would decrease the amount of road rage and shootings. Biking can change the world.
