My greatest economic asset is the years left in my career. For ~$1500/year I insure that. It's not cheap, but it would pay out until I was 65 at some reasonable percentage of my normal salary in the case I was severely injured, or otherwise unable to work. Anywhere from an ergonomics caused hand/arm injury, a bike-riding caused head injury, a wood-shop caused eye damage, etc.
Consider grabbing it while you're young and working in a lucrative career.
