Vince Jackson was one of the athletes that had been personally selected by Dai Li. She was only 19. Vince Jackson was considered slightly above average in terms of her strength and talent. The reason Dai Li chose her was that he fancied her malleability.
There was no advantage to being 19 in the adult shot put competition. It could even be seen as a disadvantage. Shot put not only required strength, but it also required athletes to have a certain weight. At the age of 19 the body had not yet accumulated enough fat and the development of muscles had only just begun. This may it more difficult for young athletes because they were up against people in their mid-20s, the physical prime of one's life.
