Deep Purple rocker Ian Gillan refuses to lead a traditionally healthy lifestyle, because drinking alcohol and smoking cigarettes works for him.

The 60-year-old SMOKE ON THE WATER singer also dismisses any suggestion he should take up sport, because he likes to save up his energy for thinking.

He explains, "I drink pretty much only beer and smoke cigarettes. Also, I like to go swimming and walk the dog.

"But I hate jogging, because there's too little oxygen left for the brain, you can't think anymore."
