I said golf was much less demanding physically, not raising a child. I did say having a child may affect Roger mentally more so than physically and that is of course debatable but I will give you my reasoning if you like. Physical and mental aren't two arbitrary concepts at all, they are quite clearly defined with aspects that differentiate each.. and yes of course they can both affect him as well and the state of one can affect the other, I never claimed contrary.
As for golf versus tennis, I don't care you can pick whatever sport you want, football, basketball, team or solo; you have the weight of your own expectations, your fans, and the world on you and you have clutch moments that you better perform. What sport at the highest level in the world isn't mentally demanding and how can you weigh the demands of one against the other?
You said that golf was less physically demanding than tennis, but not less mentally so, and the mental
aspect is what would affect a new father more
anyway. That's what I was referring to, and sort of disagreeing with. To me, physical and mental experiences are deeply entangled, no matter how much we're conditioned to separate the two. As for golf, like I said, I don't want to get into a debate about it. I'm of the opinion that golf is a ridiculously overrated sport in terms of mental strength. But you are certainly right that any professional athlete faces extreme pressure, and it's silly for me to try to compare or quantify the level of pressure.
