On one level, this is a great advertisement for aikido’s effect on personality if not fighting ability. Having said that, the MMA guy is equally respectful. Constant investment in loss seems to grind the ego down rather effectively. Question: would a Tomiki or Yoshinkan Aikido guy do better? Probably, but not much. Makes me think, perhaps Aikido and Taiji share a similar evolutionary history: its possible they both started as weapons arts (certainly the case with Aikido) and the unarmed aspect only makes sense as a last ditch set of techniques intended to defend against an armed opponent?
