Yes yes yes, could very well be impacting this..I just want to make this further point to all who have daughters and granddaughters alike to impress on them the importance in the youth and on into 20-30’s that is the time to really be really building their bones. That’s your reservoir for later, but all should continue with exercise ongoing after that.
With all the phone use , social media craze as doing more tech stuff even if it’s good stuff, and kids not participating in sports ( not to having pick up basketball games hardly any young people play tennis anymore , etc) as doing more tech stuff , even if it’s good tech stuff. -They are setting themselves up for issues down the road!! It’s not easy to motivate them if really attached to this stuff. Be diligent, be a nag…. Someday they will thank you, or maybe they won’t have to because the issues May not arise!!!
