This is a really well thought out article with great advice. I especially enjoyed how you propose more adaptation to the individual and her or his needs. No hard and fast rules. Just some advice with lived in experience.
Funny thing is, I’m not a coffee drinker, but I am a tea drinker. So, much of what you suggest easily applies to this as well. Green tea with some mint for me.
50 claps, a great read!
