We all remember Brian from his first appearance in episode 37, but while that chat was about his personal story, this is him bringing his incredible professional knowledge to the table.

He explains to us what happens to the body and brain during periods of addiction and stress, and the scientific tactics that can help us all battle those things. He also explores why we end up in those states in the first place.

Brian also tells us about his MAVIG system, a set of principles and techniques he keeps in his daily life to manage his physical and mental health. Brian brought a lot of fascinating information with this one and it was a real eye opener to hear about the things we can all do every day to improve our quality of life.
