I'm hopeless once it gets over 40. Twice had to retire hurt due to heat exhaustion on a couple of 42 days. First time was a semi where I was going nicely on about 40, but standing at the non-strikers end in the last over before lunch it hit me and I had to go off before I fell.
Other time was a similar day. This time made it to the break, but just went and stood in the shower with my pads still on and didn't come out.
Yeah I know - softcock. Never really been too badly affected in the field, but batting in those temps, I got nothin.
