I can tell it has been hot in the USA by an upsurge in izzers sales at amazon!
Science has shown that after giving it your all for over an hour in the heat that you are playing, mentally, as if you have had a concussion!
This is temporary, causes no long-term harm usually, but makes keeping score very hard.
That is, it suddenly becomes difficult to know what the score is, even if you had no trouble the first set.
Makes me happy thinking of all the players who can keep having fun out in the summer heat!
