I was reading Batman & Captain America (great book!), and I came across a page where Batman as Bruce Wayne said that Steve "seems almost to have a slight edge". Does that slight edge refer to Steve's Super-Soldier-Serum-enhanced physique ? 

Thanks in advance! 

Did you or do you train any martial arts?

To clarify, I use "martial" to include any and all military, combat, empty hands, weapons, tactics and strategy.

Being a wuss does not disqualify you or anyone.

Almost any training can be divided into 3 aspects, the physical, the mental and the spirit (the living essence).

My take on Captain America (of so long ago), who is physically perfect due to the super-soldier serum, would be training exclusively on the mental aspects. He would require minimum time to employ proper techniques. 

Got to go, more later.
