Interesting to me anyway. Dairy farming has come a long way since the days of milking by hand. I can remember as a kid working on my uncle's farm, being so tired at the end of the day and we still had to do the milking. We finally developed a system that really helped. We trained the cows to jump up and down and all we had to do was hang on. Took a lot of the strain off us when really beat after a day in the fields.
