Fasting Discoveries

I realize I've only fasted two nonconsecutive days, but I've learned a few things.  Or rather, I've discovered some things about fasting in relation to the physical that completely surprised me.  I never expected:

• hiccuping
• gas
• exhaustion
• difficulty in speaking, thinking
• inability to get warm
• increased sense of smell

These are all the things I can think of now, but it's weird, all these things.  Just thought I'd put that out there.
