Both parents 18. Divorced when I was 8, fought eachother over petty bullshit for years after. I raised my little sister, who was born just 3 years before they separated. Depressed, medicated for anxiety, and have no relationship with any of my family.
If I had my current knowledge, low-level iron forging, agriculture, and architecture (cisterns, wells, deep food storage) and very rudimentary medicine because the wife is obsessed with various herbs that are used to make our modern medicine
If I was starting from scratch, probably just be decent at hunting because I have good hand eye coordination and maybe tracking
