Any hope for over 50 years with no job experience?

I have been a SAHM for almost 30 years, the last 15 years in the UK. I have only had a couple of part time jobs at Blockbuster Video for a short time in the US.

My soon to be ex-husband is pushing the idea that I should easily be able to get a job once divorced. I do have a science bachelor degree but it is outdated and the knowledge wouldn't really transfer to the UK due to being geographically dependent.

I have seen a lot of talk and my children have also talked about CVs being sorted via AI and often experience is the first way to trim it down. I can not see how any CV I could put together would not immediately be put in chapter 13 by a business.

In addition, I have health/joint issues that mean manual labour or any job that requires standing for a too long would be physically difficult.

Any suggestions on how I could get a job, particularly in an area with high unemployment already? TIA
