He showed no capability of recovery after the fall. His efforts were entirely uncoordinated. If his SS agents and aides didn't help him get up, he would still be flopping like a tuna.
Very distressing to see.
Not catching yourself when you fall is a sign of neurological problems. I have a neurological disorder and I don’t catch myself when I fall. Catching yourself is a reflex, and reflexes come from the spine, according to my doctor.
