I think others have covered what I was going to type.
While we await western medicine catching up with TCM regarding time spent stuyding pu-erh then I'll stick with the TCM guidelines.
By sticking with the guidelines I mean drinking whilst being aware that there may be potential downsides, much as I smoke or drink alcohol.
I suspect a large scale scientific experiment might prove that loads of young sheng can give you a sore tummy.
The other issue is that a proper scientific study is unlikely to be around for some time. As in a study of 1000 people drinking sheng over 5 years showing little ill effects will provide little light on the effects of one person drinking it daily for 50yrs.
One of the intentionally aged teas, Pu-Erh has a loyal following.

1) Exactly what is considered young sheng ? Spring 2008 ? 2007 ? 1999 ?
Sheng that is less than 10 years old is too young to drink.
According to the "local" teamaster in Seoul, Sheng should not be drunken much younger than 17 years old in order to "get its full benefits." Shou should be at least 10 years old.
