How cute is that donkey!
Cold showers reminds me of a nine month period where my hot water service broke down and I couldn't afford to fix it. It was great, but that was in the tropics.
It is amazing that you are doing so many things that will affect your health positively.
I have also wondered about intermittent fasting, but never tried. Also, perhaps the reason snacking with the meal is better, is because it gets mixed with volume with the rest and most ends up leaving the body. Snacking between means the stomach is empty and will absorb more?
