Over ambitious parenting

The current issue of the excellent Junior magazine has a short piece about how a father's parenting style and influence his child's career choice.

On the same page, there is a piece about a 6 year old boy from Mexico who is already an expert (though the piece doesn't go on to say how this has been determined) in diabetes, osteoporosis and anaemia as a result of studying medicine on his own.

He now wants to become a doctor and has applied to go to university but, quite rightly, has been refused a place because he is too young to study at such an advanced level. The refusal to allow him to study is now to be challenged in the courts.

I wonder what his father's parenting style is if he is prepared to deprive his son of a childhood and what future career awaits him if he is burnt out due to stress before he is even a teenager as a result of relentless pressure from an over-ambitious father?
