Many thanks to you all.
Hi Paul, Pervaz,
Sorry for my ignorance, but can you please tell me the advantages of Aikido/Systema compared with Karate-do or Judo?
Hi Paul,
Yeah, I finally figure out I may rest better if I fight harder. 😀
Seriously, I believe learning such martial arts will improve my concentration and discipline, which will help my trading. Besides, after a few accidents in the area, I think it is a good idea to learn some sell-defence skills.
