He'll be back in the field before midsummer, I bet money on it. I've done a lot of work for farmers missing limbs or parts of limbs throughout my life. They see it as just another thing to deal with, like weather or mechanical breakdowns. I've also been to a couple of funerals for guys that weren't so fortunate.
Life on a farm is not easy. Between the chemicals, equipment, animals etc there is always something that wants to kill you or maim you.
Quoted for truth. My wife and I are on casual first name basis with the chiropractor, urgent care nurse practitioner, and one ER doctor. Mainly her, since she is full time homesteading. But when it comes to the heavy lifting stuff, that's me on weekends and summers. If you weren't familiar with the life, the amount of deep cuts/lacerations, bruises, muscle strains, burns, and fractures would amaze you. I have a lot of family in Illinois and Minnesota who farm large parcels (thousands of acres) and the number of missing fingertips and scars makes you go "wow." And they act like it's no big deal.
Farming is very safe. In fact it’s best to work with your head in a phone and a neck tie on. Guaranteed to be safe!
