Ask HN: 36 years old, no skills, no job – what can I learn?

I was making $170k in biotech, doing operations. This job was not enjoyable and hard to quantify/describe. Basically, just putting out fires all day. I got laid off and biotech sucks right now. I'm prepared to retrain, but I want to make a similar salary. Unfortunately tech seems to have downturned as well - so I'm not sure what to do. I had some contacts at some SaaS companies that peripherally served life sciences, but this seems to have fizzed out as well. Also, did some sample work for equities analysis in life science, no response.
