Rate of falls in elderly increases

This is odd. Falls are a big risk for people my age--that's not news. But I wonder why the rate is so much higher now than when my grandparents were in their 80s (died in 1983). This author's opinion is the soaring use of prescription drugs. Fall risk drugs are called FRIDs. Mortality from falls has increased much more in the US than other high income countries. https://jamanetwork.com/journals/jama-health-forum/fullarticle/2837039? 

"The surge in deaths from falls in the US reflects a new phenomenon. There is no reason to think that older adults today are much more likely to be physically frail, have dementia, have cluttered homes, or drink alcohol and use drugs than age-matched adults 30 years ago, and the percentage living alone has not changed much since 2000. On the other hand, there is plenty of reason to believe that the surge in fall deaths may be tied to the soaring use of certain prescription drugs,3 which is a risk factor that, unlike most other factors, clinicians can readily modify."
