Yes. I returned and took my degree - Environmental Science - as an adult and changed career on the basis of that degree. There was a good deal that was directly relevant but, more significantly, I found it VERY clear certain others that I was working with did not have that academic background and were making some rather concerning decisions at times as a result. Overall more more noticeable through absence than presence really.

I have moved diagonally since then - after around 20 years - so it is less relevant now.
