@bearfosssils,
Interesting question....since I was young I was always scientifically curious. During my formative years I had a specific person (stepfather) who told me I was to dumb to accomplish great things. For me forensics was the ultimate challenge and I set out to proof him wrong. So I started while an undergraduate working as a cleanup guy in the morgue and wound up getting a free education from a forensic pathologist.
Advice? Guard your heart and mind, the tragedies of others should not require you to sacrifice your own wellbeing. Be curious and unafraid to learn new methodologies. Don't be afraid to get dirty, assess those things that make others flee (decomposing bodies, mass killings, dead children) ALWAYS SEEK scientific truths in the horrors of death. J
