Billionaire business mogul Donald Trump refuses to touch booze after losing his beloved brother FRED to alcoholism.
The tycoon-turned-reality TV star watched his older sibling struggle for years with a drink problem, which eventually claimed his life.
And the 64 year old admits he has never been tempted to sip even a drop of alcohol, after his brother repeatedly warned him to stay away from the bottle.
He tells Piers Morgan, "I've never had drugs. I've never had a cigarette and I don't drink coffee. I have other problems, I guess!
"I had an older brother named Fred, who was a great guy, a handsome guy - the most handsome guy that you've ever seen. He had everything going: he loved flying airplanes, he was a professional pilot. Somewhere along the line, I think he was in college, he started drinking. It got worse and worse. He also smoked a lot.
"He was about 10 years older and he would tell me, 'Don't ever smoke, don't ever drink.' I say that to my kids now - no drinking, no drugs, no alcohol. So far my kids have been following my lead.
"I had this great brother who had everything going but he became an alcoholic. Ultimately, he died. It was amazing genes that he lasted as long as he did. He was a very severe alcoholic (but) he was an amazing guy.
"In a certain way, he was one of my great teachers, if not my best. He got me not to smoke, not to drink. I say to people don't drink. It's not hard."
