@Izzy78 - That is quite a story. I imagine it was one of those stories that the class was stone dead silent once he talked about the seniority he had. I know people that have dug ditches and they have said that it is the worst job they have ever had doing it by hand. It hurts really badly on the back and they have told me that they have gone to the chiropractor several times for him to adjust the same vertebra. The chiropractor has also stated that this is common among those who dig quite a bit, them injuring the same vertebra.
