Hey Texas State University - Did you know? The 'lump' you feel in your throat when you're scared, nervous or crying is a fight-or-flight response that causes your airway to expand to provide you with more oxygen. Don't worry though, this won't happen to you today because you came to see TxDOT at the #TxSt Career Fair at the LBJ Student Center! We'll be here from noon to 4pm! #TxDOTCareers TXST #SanMarcos #Momwouldbeproud
