ATTN: JOE ROGAN and all UG re: Rickson

If you have a question you think Joe should ask Rickson on his show on the 21st, post it here.

My question: What do you think is the most important concept in jiu-jitsu that can be used by people who CANNOT physically train? (Because they're too old, sick, or whatever.)

Another question: Please talk about your training with Orlando Cani.
