Physical Skills Become Social Media's New Currency of Achievement

People are sharing videos of themselves doing difficult physical skills online.

These include handstands, pull-ups, splits and skating tricks.

Such skills are easy to understand because viewers can immediately see whether someone can do them.

Learning a skill also gives people a clear feeling of progress.

The videos can show qualities like strength, discipline and bravery without using many words.

However, seeing impressive feats all the time can make ordinary achievements seem less important.

Some people may begin exercising mainly for likes, comments or attention.

The experts say physical skills can be valuable for personal reasons, even when nobody is watching.
