<p>Has anyone ever heard an explaination for why nipples harden when people get cold. Wouldn’t they do just the opposite?</p>
<p>density decreases = harder?</p>
<p>And to think, I opened this thread thinking it would be about the part of Phaedo where the nature of death is discussed.</p>
<p>“Small non-striated myocytes (muscle cells) arranged cylindrically within the nipple are responsible for this erection of the nipples.”</p>
<p>that’s all i could really find…nothing specifically about cold</p>
