Hi,
I'm in the middle of this series which I think may be extremely helpful to anyone. It's free for the next 5 days. It's about how the bacteria (or lack thereof) in our gut affect our health. The new science is amazing and may show you how you can get help to improve your health. If we don't have the right bacteria in our gut/intestines our health can suffer.
I knew a little but this has much more.
Recently different groups do a 7 or 9 day video series of very interesting new medical ideas on health where they interview both doctors and patients but mainly doctors and have animation where needed. Each episode is only free for 24 hours and usually they then have a week-end where all 7/9 episodes are again shown once. They make their money by selling the series and offering it "cheap" while it is still showing - but you don't have to buy to watch initially.
It's very helpful just to watch and learn. I just watch and don't buy.
Google:- Interconnected series.
Well worth a look.
