Today would have been Ramon’s birthday. ❤️
13 years gone, but never forgotten.
He fought the very best, anywhere, anytime — and always believed in one thing: they never truly beat me.
That was Ramon. That was his mentality.
Happy birthday, champ. 🥊❤️
Forever missed. Forever remembered.

Back at Lumpinee after all these years. 🇹🇭
37 years ago, I was here at Lumpinee with my stepson, Ramon Dekkers.
Today, I’m back — this time at the new Lumpinee Stadium in Bangkok, together with my son Nick Hemmers, Ramon’s half-brother, and my grandson Dani Hemmers.
A different generation. A different Lumpinee.
But the same family, the same passion, and the same love for fight sports.
Three generations. 37 years of history. ❤️🥊
