I always wonder with pcs and treatments .if it matters which part of the brain was damaged .mine is left side of my head above my ear .different parts of the brain do different things so maybe it takes different types of therapy for different parts that were injured . as for strength training in all that jazz .im 6,2 215 with a 32 inch waist .I even wrestled from first grade on. Made it to state twice. Let me tell you nobody has a neck like a wrestlers neck. I'm sorry to say in the 70 miles an hour rollover it didn't help too much . exercise and eating right I am all 4 . cos it can't hurt it can only help right .remember were not sprinters anymore. we're like long distance runners. we must all pace ourselves to our own needs. hope this helps .
