Not necessarily. No not at all. Introverted sensing doesn't lead people to live so called healthy lives. For instance, most of the smokers I know are introverted sensor types. Many over eaters are Si types as well. Si is about cognition of states of physical being, with an emphasis on comfort. Comfort does not equal health. I find that lots of SEI talk about being healthy habits, but the default position reins supreme. No offence guys.
