Re: the coffee, The hell you say. It’s not about caffeinating for me. It’s about just enjoying a cuppa. When I’m out, I do without and drink herbal teas. But when I get some in, it’s about enjoying a simple pleasure. The others on this list, some I am already doing while others are interesting. Oh and the cold showers, I live on a tropical island where it gets hella hot. Cool showers are essential.
