* Friendly reminder: Misconceptions, false information, and myths can be easily spread and are difficult to dispel! We would like to encourage and remind our visitors to always 1) evaluate information before sharing and 2) keep the focus on just the facts instead of restating and rebutting myths, as this has the potential to unintentionally embed and spread myths.
