Why Multitasking Doesn't Work - Forbes

A timely reminder

"Unfortunately, our brains just aren’t equipped for multitasking tasks that do require brainpower. Our short-term memories can only store between five and nine things at once.
When you’re trying to accomplish two dissimilar tasks, each one requiring some level of consideration and attention, multitasking falls apart. Your brain just can’t take in and process two simultaneous, separate streams of information and encode them fully into short-term memory.
When information doesn’t make it into short-term memory, it can’t be transferred into long-term memory for recall later."
