Each person has their own temperament, but it doesn't mean that it stays the same throughout your life. A child's temperament is generally closer to sanguine, but becomes more choleric during adolescence. Your organism becomes dryer as you age, so an adult is more prone to melancholy. Finally, in the old age, the body is still dry, but it tends to ooze an increased amount to of phlegm, indicating a more phlegmatic temperament. We also go through a similar cycle each year; spring, being ''hot'' and ''moist'', intensifies the sanguine temperament; summer, ''hot'' and ''dry'', aggravates the choler; autumn, which is ''cold'' and ''dry'', reinforces melancholy; and winter, being ''cold'' and ''moist'', helps the phlegm to build up. It's important to keep these ageing and seasonal changes in mind when developing a sound dietary regimen.
