TBH I wasn't surprised by what he could achieve. I wouldn't describe him as having no arms. He clearly does have arms but they are shorter than they should be and he has no hands. My elder son was born with one 'normal' hand and one like that man's - no hand and the forearm is about half the length it should be. There is nothing that Richard can't do other than the button on his right cuff (it's his left hand that is malformed). He's been bungee jumping, abseiling, swum in galas, played basket ball. He took music for Standard Grade which included playing the guitar and keyboard. Between doing his first degree and his Masters, he worked as a builders' labourer during the day and a chef in the evenings and weekends so he could pay off some debts. He drives a manual car and refused to even consider learning in an automatic. Last year, he and his wife did a 3000 mile sponsored mountain bike ride round Asia.
It's all about attitude. Through Richard and many.many visits to hospitals and limb centres, I have met numerous children and adults with similar disabilities and what they could do is astounding.
I though the man in the video had parents with exactly the right idea: they didn't treat him any differently to his siblings. I was the same with Richard and I used to get cross with people who thought I should let him get away with more than his siblings. Treat a disabled person as if they are the disability and they are more likely to become that disability. Treat them like you would treat anyone else and they will become like anyone else.
Good on that farmer though. He has the right attitude. and what a lovely smile.
