It's always great to continue learning, but honestly it would be ridiculous if she’s considering going back to uni full time for a science-related degree when she's 26 and she's never had a job (other than Youtube). She should just keep learning casually on the side whilst she figures out what to do with her life. Maybe it's harsh, but I couldn't help but roll my eyes when she talked about going into the sciences at university level. To me it just sounds like more putting off/procrastinating choosing a career path by turning to the only thing she knows - school.
I also agree with the comment above me; casual science courses are fairly accessible, but there comes a point when pretty extensive proficiency in maths is required. Definitely not an easy thing for someone like her who probably hasn't done any math since high school.
To be clear though, I don't think there's such a thing as being too old to go back to school to retrain, and I think more people should enjoy learning for the sake of learning and becoming more knowledgeable. But in Jess's case, it definitely doesn't sound like she has an end goal in mind to potentially going back to uni at some point other than to pass time because she’s bored and doesn’t want to get a “real” job.
