One of the most striking features of death is that it reverses age differences.
My brother was 2.5 years older than me. In childhood, this is a serious difference. My brother was always so much taller, stronger, more clever and informed than me, bigger than life. He was an authority, more human and understandable than the divine authority of our parents. I could entrust him things I would never tell my father or even mother. Throughout our early and teenage years, he introduced me to life, helped me discover the world we were living in.
After his death, our age difference slowly diminished. Last year, I reached his age, as if we were twins. Now, I am already 42 while he stays at age 41 forever.
I still cannot really believe it.
