I have been told by people before to watch the eyes but whatever signs people give out from their eyes I don't pick them up.

I was told that if you take your eyes off their eyes you miss it when they are in pain. However, I'd rather know if they are throwing something than how they are feeling because I'll be aiming to do the best I can in whatever situation and in my midget weight class there are relatively few KOs. Some people can pretend they are not in pain when they are anyway.

For some reason I prefer to look at the shoulders more than anything else but in general as others have suggested I think a body part which has a direct functional role in the boxing action is more informative.

I might trial watching other areas too to see if i pick up more. Thanks for bringing up the topic because you have me thinking now
