I believe that no matter what age you start dancing at, you will somewhere find yourself happy to study dance and enjoy every moment of it. Every dancer’s journey is different. Typically, ballet dancers start studying as young as 4 years old, but this is not a rule even for professional dancers.
As you said, you used to do ballet a few years and still have the skills, technique and flexibility, it is a plus point for you to start dancing again. Go for it!
You can start again if you want. You will need to start in a low level class and work your way back up again because I highly doubt you've actually kept your technique.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
