Dehydration

Last night after dinner but just before leaving to teach swimming I made a small mug of Ovaltine. I suggested Bill have a taste He said no thanks. I said You like malt in beer but I like malt in Ovaltine. Have a taste. He had a taste and fainted. I was right there next to him so I caught him under the armpits. He remained vertical. It was a vertical faint. When he came to I suggested he sit down and I explained what happened. He said really? I thought I was having a conversation. I was ready to call off my teaching due to medical emergency. He said No, I'll be fine, go teach. I told my supervisor what happened and she said, Go home it's fine we can cover for you. I said, let me call to check on him since I have a few minutes before my class starts. Bill said he was fine and he sounded good. He was reading about syncopy and realized that he had been dehydrated and on his feet all day and then stayed late on his feet for a meeting after school. Ever since his fancy Contigo thermos was stolen 2 weeks ago he has had trouble finding a workable solution- all of our other thermoses don't stay as cold or they tip over and spill. I said order a few! (My Jewish impulse to buy in bulk). He ordered one at a bargain price and we are picking it up tonight.
