    Thanks for this Video. It's a very good explication of the items.

    I write from a Prevention Unit about Addiction located in Siena (Italy) in the Public Health Local Division (Azienda Usl 7 Siena).
    We would publicate the embed of this video in our site www.insostanza.it.
    We guess: is it possible to us to traduce the english subtitles in italian and then send to you those subtitles for a publication in the YouTube video?

    Thanks for answer
    Francesco Sanna
