hey guys. this morning an owner of the deli i keep my stuff at asked me to cut his front lawn. the slope is about 30 - 40 %. and is in the dirrect sunlight. slope goes right towards the house from the road. the area i had to do was about 15 - 20M sq ft. i am not sure. well i got cutting and got about half way done. i was sweating really bad, and i kept goin. got done with the whole front and my face was burning or stinging me. and my neck was all hot. i had to go and sit under the garden hose for about 10 minutes. and even then when i went back out there, i was burning up. i have to cut it again before the 4'th so i didnt trim. i just blew the walks and drive and left. but man was i hot. you guys ever get like that? where your skin burns or stings? what do you do when that happens? or what is that a sign of?
