I think that Piccolo probably meditates on a daily basis, and that’s cool off course, but Piccolo seems to overdo it, he probably meditate all day until something important happen, he must be the most conscious being on the earth and beyond.
I like how he only need water to survive and probably he drinks only spring one ’cause he is obviously aware of the importance of good water for one’s health. Piccolo lives smart and chilled out. Maybe that’s why he and Gohan are so fond of.
Stay imaginative drink good water and meditate and all will be fine.
