english: Scientific reason is that this notion from neuroscience of critical periods -- that if the brain is older than four or five years of age, it loses its ability to learn -- that doesn't sit well with me, because I don't think that idea has been tested adequately.
non_english: Znanstveni pa je, da me trditev nevrologov o kritičnem obdobju možganov -- možgani, starejši od štirih ali petih let, naj bi izgubili sposobnost učenja -- ni prepričala, saj mislim, da za potrditev ni bila primerno testirana.
