I had lost track in the mid 40s, in mid 50s now.
I built a model to predict SNP and due to some technical error (network connection lost), blew up some 470,000$ in 3 hours trading futures. Had mortgage, wife/kid to support etc. Was bit rusty on java/c++/c#. So took a coupe of udemy courses to brush up. Hit gym, started running to get boost. In 2 months landed job at a start up in NYC. After that took a contracting position at a bank, and now contracting for another bank (both in NYC). Also developing code generation from english specifications on the side. Still running my SNP model. So its doable.
1. Hit gym, run
2. brush up and take up a job
Its not too late. All the best.
