Re: advice for those starting the journey...
Buy plenty of dogi, atleast 3. Rotate use between the 3, and your dogi will last longer. More importantly, you will have a clean Gi to train in. Good for you and better for your training partners.
Dont leave a wet Gi in your Gi bag to fester into new life form.
Dont leave your Gi in your car when its cold. Unless of course you enjoy a cold Gi misogi before you train.
Ask the question "what happens if I let go?" only after you have a fair degree of understanding of ukemi.
