I have newly diagnosed osteopenia

.
I happily toddled in for my DEXA scan the other day, knowing that at my last scan in 2018 I was nicely above the age relevant line on the chart. I do a lot of weight bearing exercise (as noted in previous my post), and lead a quite active life. But pride goes before a fall (boy I must watch out for falls now) and I am now below the line for my age (65). T score femoral head is -1.2, and lumbar spine is -1.5.
I confess to feeling a bit bummed out about this, even though I know it is very mild. Just not what I was expecting given previous better results.
Any advice?
