Dr. Ian D. Marder:

Yes. I concur with that. It is up to the age of 25, by which I mean up to the 25th birthday. In some countries, it is a bit different. Ultimately, it is a political question as to how high an age we want to include. The higher it is, the greater the number of people who lack full cognitive maturity will be included. This is why in some countries where something like this has been done, there might be a slightly different age. The Netherlands has done something similar around young adults, and it is up to and including 23-year-olds.
