Eating grass

[Sirius]

Things that seem plausible from the earlier posts.  I'm sure there is more, personality traits and things.

• Eating strange things 
  
• Unusual growth patterns
  
• Unusual appetites
  
• Excessive crying or eerie silence
  
• Sudden personality changes.
  
• Apathy or detachment from loved ones.
  
• Sudden knowledge of strange languages or wisdom they shouldn’t know.
  
• Sleepwalking into nature
  
• Unusual sensitivity to animals or nature
  
• Sudden illnesses or fevers followed by wisdom
  
• Suddenly disappearing and reappearing
  

For quintessentone benefit, the next step would be to start scoring and matching items listed with known cases and look for patterns.

I'm sure this has been done. If anyone knows of such a list please share.
