UFC mma fighting is the most physically and mentally demanding sport in the world

So let us take a look at the topic we are debating and the resolution that must be resolved. My adversary claims that"UFC mma fighting is the most physically and mentally demanding sport in the world"So let us look at what he is really stating. He is stating that MMA is not just the most physically demanding sport or the most mentally demanding, but both the most physically and mentally demanding. The "and" in that sentence is the key factor. That means if one other sport can be shown to be as much or more physically demanding or as much or more mentally demanding his argument is invalid. He says "the most", not "one of the most". So his burden of proof is to show that this sport lives up to his claim. My job is to build my own case and offer rebuttals. I do not have to show that mma is not physically demanding, nor mentally demanding, I just have to simply show how some people and other sports can be just as mentally and physically demanding as MMA. Some of his claims are as follows1. It is mentally tough to have to be able to look in the face of someone you are about to fight2. You have to be away from your family for long periods of time3. You have be physically trained to the highest degree to do this sport. 4. It requires high reflexes. So to sum these up, I will not deny that MMA is both psychically and mentally demanding. That however is not what we are discussing. We are discussing that it is the "most" physically and mentally demanding. He has gave examples as to why he believes this. So let us examine the word subjectivity. This is directly relevant to what he believes is the "most" physically and mentally demanding sport. For him to be able to prove this point, there would have to be a gauge as to what the most physically and mentally challenging conditions are. I will give you an example of what I meanExample A : Being away from their families can be tough on the mindExample B : Spending weeks at a time learning wind patterns in order to hit a ball in the right direction can be tough on the mind. Both of these are mentally demanding and relevant to the person that is doing the task . What could be mentally demanding to one person or psychically demanding to one person is not necessarily the case across the board. So the definition of what is physically and mentally demanding is entirely subjective. So to say it is the "most", is a fallacy. Point 1: MMA athletes have to train away from their familiesPoint 1: Football athletes have to train away from their families. So by his line of logic, I can claim that football is the most mentally demanding sport in the world. The point I am essentially making is that different sports can be considered to be as much of a challenge as MMA. To say it is the "most" is merely a personal opinion, because there is no gauge to judge this other than his own perspective. Some sports that require psychical effort.1. Hockey ( the ability to balance on ice while maintaining peek mental awareness)2. Basketball ( one of the sports that requires the most cardio)3. Cross Country ( pure cardio)4. Football( a mix of cardio and mental awareness along with decision making)If you ask one of these players is there job tough, they will tell you yes. Each have a different definition of what is psychical and mentally demanding. If you were to place one athlete into another position, they would no be able to fulfill the role because they are specifically training for that sport. In conclusionWe can logically conclude that most sports are psychically and mentally demanding. My adversary disagrees and says that MMA is tougher than the rest. He has yet to fulfill his BOP and show how this is the case. I have shown that each sport is directly relevant to the person performing it and how what is psychically and mentally demanding is entirely subjective. Thus the most logical conclusion is that MMA is not the most psychically and mentally demanding. It can possibly be considered one of the most, but with no way to gauge it, we can only label it simply as just psychically and mentally demanding.
