On a dull rainy morning at the beginning of April 2001, I had got up in a rush. I had student experiments on the first hour of the morning so I took  a quick shower, I decided to wear my newest acquisition, a heavily used G-Shock DW-6600, which I had revived with a fresh battery the other day. It was 8.12 a.m., I rushed downstairs, grabbed my backpack and my coat and soon after I jumped on my, “Cold Ice Plumb” TREK mountain bike. On 8.24 a.m. I reached the traffic lights entering the centre of the city. At the green light, I accelerated so fast, that in the next turn 100 meters further my cycle-computer told me I was doing over 25km/h.
