Hey Sue,
I had my 2nd at 30’s as well.
Studying at older age, It shouldn’t be a big problem in western countries. It could be in most of asian countries. You might be over thinking. Plus you are asian female, you will look 10 years younger than your real age anyway.
Focus on your goal. You actually absorb material better. You know what information is matter. You value your time better. There are benefits from it.
What keeps us young?
No, it is not Le Mer
Curiosity, the thirst of knowledge will keep you young.
Cheers,
Ronnie
