Not really. :) Basically I am very new to it and know very little... Personally

But I can see how it could greatly effect toughness and infact EVERY aspect of existance.

I think largely how meme (ryhmes with dream) determines belief and thought and that will greatly effect ones ability to step out of the fearful survival mode in fighting and to perform like great athletes do who are not 'fighting for thier lives'.

Fear (and all the ways we deal with it) helps people fight as opposed to run or be paralized by it.

But I think getting past the stage of survival in the ring opens the doors to greater performance.

I think thier are many levels but survival would be the lowest.

-without getting into detail or explinations I guess meme would make up the subconscious mind and therefor feed the conscious mind its thoughts, beliefs etc

I think meme makes up the mind in a similar way that genes make up the body (not exactly litteral).

Its still a new enough paradigm that most will simply reject because it doesn't fit into the glass they have that is already full with what they know.

So if you're interested check it out for yourself. :)
