Dissociation 6f's (drop Attacks/catatonia)

Hey comrades, does anyone know of strategies to activate the brain? Easy ones, less games more stuff that can be practised easily. Meditation? Or other techniques. I feel this capacity has reduced. I was able to access more information two years ago, now this has reduced. Yes I am aware that there are so many Methods, books on this topic. Someone who actually practises these stuff in a daily basis is more interesting. What do you do to keep you concentration level high? Shankara
