London, Nov 18 - Legendary British musician Sir Elton John has urged youngsters to practice safe sex and be vigilant about the dangers of AIDS.

The singer, whose annual fundraisers help people already battling the deadly virus, has warned teenagers that many among them are still not aware about the dangers of unprotected sex, reports contactmusic.com.

'We are finding that too many young people are not listening to what we are saying. It's a cynical thing. Every 10 years a new generation comes along and you have to re-educate them,' he said.
