In the preceding several hours, I had taken a hike, did some calisthenics, took a shower, ate supper, watched TV, ate a candy bar,
and was reading before going to bed. It was hot
and humid, so I was sweating quite a bit. The taste of my sweat was startling - I can't remember it ever tasting sweet like that. I have a vague memory that sweet-tasting sweat is a symptom of something bad - my memory comes up with Heat Exhaustion or Diabetes.
Thanks.
