Mine's usually about 105/60 - although once it was 85/50 & the nurse looked at me in a concerned fashion & asked me if I felt OK. Family history of low blood pressure - occasionally I get the spots-in-front-of-eyes thing when I stand up, although not so often since I've started doing more exercise.
Osteoporosis: I do occasionally worry a bit about this, because AIUI cycling *isn't* good anti-osteoporosis exercise, because it's not weight-bearing. I'm pretty sure I still walk around more than the average car-driving person, though.
If you are worried about osteoporosis:
1) Women should make sure they weigh enough and exercise little enough to allow menstration. (Try an 'ovulation break' mid-cycle if doing much Audax & other riding)
2) Walk more. Try to improve the weight-bearing quality of walks, either by running or by carrying a heavy rucksack. (Half an hour with 20kg groceries might be enough, especially uphill.)
3) Make sure your calcium and vitamin D intake are sufficient. Get a
bit of sunlight to allow vitamin D to form in your skin.
4) Excess alcohol is bad for bone density; avoid.
5) Hold on to your womanly parts for as long as possible.
