A study published in the Journal of Hand Therapy tested the hand strength of millennials and found young men and women today had weaker grips than those tested 30 years ago.
Occupational therapist Ashley Sinkin says she has noticed a change in the kinds of hand injuries millennials suffer.
"A lot of overuse from typing, mousing, using their cell phones," Sinkin says.
The hands of older generations spent much, if not all, of their adult lives without computers, the internet or cell phones and their definition of manual labor likely differs from that of a millennial.
For those who grumble about this generation, the study might confirm their darkest suspicions, that millennials are softer and more pale... wasting away as they are hunched over phones.
The study only tested 240 people and its author worried less about the future strength of hands and more about the overall fitness of millennials and their prospects for a healthy future.
"You manipulate the world with your hands, so they need to be working well in order for you to be able to do your day-to-day activities whatever they may be," Sinkin says.
