When your phone or computer has too many apps running — when there are too many windows open, you know what happens, right? It slows down because it’s trying to process all that info at once. 

And, when all those windows are open at once, the computer or phone can freeze up and even crash.

The same thing happens to us too when we have too many “windows” open simultaneously and for too long!

Multi-tasking puts an awful strain on our brains and it's even proven by research!
