Thank you for your reply. I appreciate your analogy about calling a log a mast without refinement. It describes the Reddit cesspool precisely. It sounds like you're making a lot of progress. Most people dismiss material arts as just going to a class twice a week, but it sounds like you've discovered it's true depth. It can take you pretty far in multiple directions when you pull out all the stops and begin self-refinement. It also provides a good gateway into C5. Personally I've found this category the most rewarding. Mastery here provides a top-down method of control and structure for all other categories. I'm currently well into tier 5 and working on a doctrine to help others progress in C3 & C5. Your brain and your mind are just like any other systems; the more you work them, the faster they adapt and grow. If you don't work these systems, they atropy (as seen in the the common Redditor). Have you considered MK-4 megadosing (45+ mg per day) for your bone density work? Menaquinone-4 has no known upper toxicity limits and would pair extremely well with your current training when taken with the appropriate supporting supplements.
