Speaking to the press, elated after her convincing title
defence, Lee replied to The New Paper's prospect of taking on
former South-east Asia Games and Olympic swimmer May Ooi, who
recently entered MMA.
"I am all game for that. I think that it would increase MMA
in Singapore even more - and I think that it would be really cool.
So, why not?"
When asked when and where she would be ready for the
potential bout, Lee joked: "Anytime! Bring it on. I could do it
right now."
2 points : May Ooi is 40 years old. Like it or not, the reality
of physical incarnation is that you're working with a physical
body, and in physical-intensive sports like martial arts, the
optimum balance between experience vs youth, is between 25 to 30
years old. May Ooi is doing financially well operating her MMA
school as an instructor, but competitive MMA really isn't a good
idea for her, and her 2 win : 2 loss record reflects that.
