BOULDER, Colo.- Tyler McKenna’s 33-year-old future self appeared without warning on Thursday, reportedly screaming at the engineering student to abandon his major immediately before he reached Thermodynamics and Heat Transfer.
“I survived recessions, pandemics, and two divorces,” the older McKenna said, visibly shaken. “But nothing compares to Thermo and Heat Transfer. Nothing.”
The younger McKenna admitted he didn’t know much about the class but described his future self as “terrified in a way I’ve never seen before.”
