Thanks for your query
Findings in your chest X-ray are absolutely normal as described by you.
These are all age related findings and these are normal in your age group.
1. Fine atheromatous plaque
with prominent aortic knuckle and dilated unfolded aorta
are normally found in hypertensive patients and deranged lipid profile
. It is due to long standing injuries of the blood vessels.
2. Bronchovascular markings and hilar vascular shadows become prominent with age.
spine also shows degenerative changes with age, this is also normal.
4. Calcified shadows in carinal region may be due to prior infection and it is normal .
so you need to be worried at all.
