I’m thinking of going back to school for Biology, but not sure. Have been thinking about it for a few years (getting older, seeing people around falling ill, and now the pandemic). Ultimately in Bioinformatics or Genomics. At least I can still utilize my technology knowledge than start from 0.
Also, the pay is less than a normal software developer.
I am extremely empathetic with you on the decision you have to make.
I am well aware that software developers on the whole have much better than average remuneration, so it's understandable that positions in other fields will attract lesser pay. However, another point which I didn't labour above (because I'm not sure if it's universal or in my own country only) is that student and junior doctors are expected to work absurd hours, often double the 48 hour per average week limit set by the EU Working Time Directive.
I'm currently (as in right now taking a break from) studying for the HPAT standardised test in my country in preparation for applying for medicine in the coming academic year. Although it's not particularly complex, I'm aware that if I had spent the time that I dedicated to my EMT qualification and now the HPAT, I probably could have added hundreds of thousands to my annual income as opposed to a decade of ~€15 ph labour.
This isn't so much a reply to you at this point as a lament about medical care is undervalued. I'm a competent software developer at best.
