When is it to hot to cut the grass?

Here in Jersey it's been hovering in the high nineties, probably hit 100* today. We are having heat advisories. Should I cut my lawn? What do people do in Arizona?
Zydo, that was just a joke. Sorry about that nasty divorce, It is sad how love can go from one extreme to the other. I bet then you felt like telling her which side of the mower to stand on.... another joke. I thankfully never divorced.... of course, never marrying was my savior.... no joke.
I just cut my grass and let me tell you the truth, it's too freakin' hot !!!!!!!!!!!!!!!!!!!!!!
