Raymond's son, David Belle, was born in 1973. He experimented with gymnastics and athletics but became increasingly disaffected with both school and the sports clubs. As he got older, he claims to have to read (as-yet-unconfirmed) newspaper clippings that told of his father's exploits and was increasingly curious about what had enabled his father to accomplish these feats. Through conversations with his father, he realised that what he really wanted was a means to develop skills that would be useful to him in life, rather than just training to kick a ball or perform moves in a padded, indoor environment.
