I was still shaking with fear day and night six months later, and though this eased out eventually, twenty years down the line the sound of a pneumatic drill would leave me trembling uncontrollably for some hours. The holes in my head are still there, though they have almost grown shut. They are only about one cm in diameter now. I still get severe pain in my head at times, especially when I am under stress. No matter how bad it gets, all pain ends eventually.
Any expert is as likely to be wrong as right.
Therefore I shall primarily rely on my own judgement. Anything is possible. Anger can be used, it's a wonderful source of energy and power. The downside of this is probably that you might also more easily die. Since then I live my life with utmost intensity, the days are full, not to be wasted.
