A certain young man started a new job in a city. He would drive every day to work, as would most of his collegues. The drive was a long one - he had to get into the city through a very congested road tunnel, and it didn't take long for before he had decied to start a ridesharing initiative with his collegues. But within a week of starting it, he found with severe pains in his wrists.
They seemed to happen while he was driving through the tunnel - he was fine outside the tunnel - but because the tunnel was so busy, they often had to spend some time in there, and it was quite a painful experience for the young man. He saw a doctor the following weekend, and he was told that he had a problem that is quite common nowadays: carpool tunnel syndrome
