The warrior spirit: Train hard, master oneself, fight evil.
Here is a visual catalogue of martial arts, comic book heroes, samurai culture, fine living, higher education and general enlightenment.
There is a way between voice and presence
where information flows.

Unlike other basic bodily functions, such as eating and breathing, we still do not fully understand why people need to sleep.
Sleep deprivation is nearly as misunderstood as sleep itself, but it can physically and mentally harm people in myriad ways. Losing sleep can cause hallucinations, psychosis, and long-term memory impairment. Some studies have linked sleep deprivation to chronic conditions like hypertension, diabetes, and bipolar disorder. In 2003, neurologists at the University of Pennsylvania found that sleep deprivation over three consecutive nights (in the study, staying awake for 88 hours) as well as chronic sleep loss (in the study, four to six hours of sleep each night for 14 nights) seriously impaired cognitive functions in healthy adults. Also in 2003, Japanese researchers found that total sleep deprivation can cause high blood pressure and has “profound” effects on the immune system."
