Quite literally. How come when we feel "confused", we start getting the need to expel the contents from our stomach?

I get that we get sea-sick because of "mixed signals" coming in to our brain. But why do we feel nauseous? How come the centre of the problem becomes the stomach, and not some sort of heightened sense of needing to find balance?

Hope this question makes at leasr some sense. Thanks!

In the Trial of the Ancestors expansion, notifications for Trade Requests, Guild Invitations, PvP Challenges, Party Invitations, and the all new Hideout Invitation have distinct icons.

"In Path of Exile: Trial of the Ancestors, you'll be able to hold the Alt key while hovering over a stack of Currency Items in the trade window to see the total quantity being offered."

"If you'd like to play a Damage over Time build but don't have time to wait around for Ailments to deal Damage, check out Sadism Support! It causes supported Skills to have less Ailment Duration and deal Damage with Ailments Faster."

Devour Support causes Killing Blows from Supported Skills to consume corpses to Recover Life and Mana.

Spells supported by Spellblade Support have added Spell Damage equal to a percentage of Damage of Equipped One-Hand Melee Weapons. Whoever said a sword couldn't channel magic just as well as a wand, anyway?
