try mowing a huge lawn, in 90 degrees weather.
Well my lawn is not huge but I love mowing it in the sun, it's a welcome break from the computer. In that heat I'd just wear shorts except for safety I'd wear thick boots instead of sandals which is a bit of a bummer. Actually to be honest you are not supposed to mow your lawn when it's too sunny, better in the morning or evening (I think, or that just might be when you are supposed to water it).
