Water your kidneys.
One conversation I had recently with a patient was an inspiration to write this post. I was asking them what they are drinking to stay hydrated throughout the day, and they told me that after they are done with one morning coffee, then another cup of coffee, that's pretty much it, then they have to push themselves to stay hydrated at all because they do not like the taste of plain water.
Cultivate your brain as you would a grain.
I think of a brain as I think of a grain (even the shape of it is provokingly similar to the shape of the brain). In order for that grain to grow you have to cultivate it, prevent from too much sun, under or overwatering or insect infestation. You may need to add special nutrition to the mix for the grain to grow into your desired plant. And then finally you put some effort into growing the grain and you see how it branches out and shows as talented leaves, petals, nectars that attract pollinators like honey-bees. In the next few months I want to concentrate on ideas on how to age gracefully or rather - how to grow older gracefully and I start with command center, the brain.
