It doesn't sound like much, for an elite athlete who spends hours exercising. No wonder he always looks a bit peaky (imo).
But he probably spends a lot of time meditating and hugging trees, so that keeps him healthy. Or something.
I wonder how he is going to cope, mentally, now all the ATP/ council stuff is coming out? It really affected him last time (at least, he used the Kermode stuff as the excuse why he lost a few matches at the time).
For someone who craves love and attention, he is really doing a good job this year at attracting negative press.
