One of the fundamental lies in Einstein's schizophrenic world:

Doc Schuster: "Time slows down for moving people."

Actually, what validly follows from Einstein's 1905 postulates is:

Time SPEEDS UP for moving people.

Neil deGrasse Tyson is teaching the same lie (which nowadays is an absolute truth after being constantly repeated for more than a century):

Neil deGrasse Tyson: "One of the towering great achievements of the human mind in our understanding of the universe is Einstein's theories of relativity. (...) It makes only two assumptions: that the speed of light in a vacuum is constant no matter who is doing the measurement and no matter in what direction you are moving or how fast. You always get the same measurement for the speed of light. That's Assumption 1 which by the way the experiment has shown to be true. Assumption 2... (...) Given those two tenets, extraordinary spooky phenomena derive from them. For example: As you travel faster (...) time ticks MORE SLOWLY for you than it does for other people who are not."

Just the opposite conclusion derives from the two tenets (assumptions):

As you travel faster, time ticks FASTER for you than it does for stationaries (you see your clock running FASTER than stationary clocks).

Here are people who do teach the correct conclusion:

Introduction to Classical Mechanics With Problems and Solutions, David Morin, Cambridge University Press, Chapter 11, p. 14: "Twin A stays on the earth, while twin B flies quickly to a distant star and back. (...) For the entire outward and return parts of the trip, B does observe A's clock running slow..."

Albert Einstein: "During the partial processes 2 and 4 [the outward and return parts of the trip] the clock U1, going at a velocity v, runs indeed at a slower pace than the resting clock U2." [Note: In Einstein's paper U2 is actually the travelling clock and U1 is the resting one, but since in the above quotation things are judged from the traveller's reference frame, U1 is said to be "going at a velocity v" while U2 is called "resting".]
