My younger brother died of a drug overdose at 50. When I got the call from our mother, I was not surprised, nor remorseful.
I was surprised he was able to live that long without someone killing him. The crowd he hung out with at various times in his life were criminals, thugs and drug addicts. And very dangerous folks. Birds of a feather.
Whenever he was around them, he was submissive, but when he was around normal people he was alpha male. He knew how to manipulate people precisely to achieve whatever his goal was at the time, be it sex, money or dope.
When he died, neither my three sisters nor I attended his funeral. He was despised by us and mom could not ever figure that out....................
Tragic...very tragic. But I’d encourage your family to remember: “scientists know more about the surface of the moon than they do about the human brain”.
