When he's not performing on stage or advocating for the legalisation of marijuana, Willie Nelson loves nothing more than to kick back at "Luck Ranch" - his home in Texas.

"When you’re here, you're in Luck, and when you're not, you're out of Luck," he joked.

More than 70 horses join him there - all of which had been destined for the slaughterhouse before he rescued them. And, with over 700 acres of land to wander around, they lead a very happy life.

"My horses are probably the luckiest horses in the world," Nelson said. "They get hand-fed twice a day, and they were just ready to go to slaughter is probably the last thing they remembered, so they’re happy horses."

Rescuing the animals is a cause very close to Nelson's heart - so much so that, in 2015, he won the People's Silver Telly Award for his music video for "The Love of Horses", which showed him meeting with campaigners working to end the slaughter of horses.

And at nearly 86 years old, the singer shows no signs of stopping his work: not in his activism, or his music. In fact, he's in the middle of touring right now, and will be spending 200 days on the road.

"It’s a lot of traveling and being away from home," Nelson said. "But that’s what we do."

He also spends time producing and selling his own brand of marijuana - Willie's Reserve - but only where it's legal, of course.

When asked whether he ever thinks about giving it all up, his answer is somewhat mixed. He thinks about it, sure - but will he actually do it any time soon? Probably not.

"I retire after every show," Nelson said. "I say, 'That's it, I'm not goin' no more,' but then we hang out awhile and people [his band] feel like playing, and so we go play again."

For now, though, Willie is happy with the way things are: he's got his music, he's got his ranch, and - most importantly - he has his horses.
