Depends how you define "chemist", I guess. I do it every day, not in the sense of fiddling in a lab but in the sense of fiddling along with people who fiddle in the lab. I am still applying chemical knowledge on a daily basis, and that makes me a chemist (sort of), doesn't it?? And, as the old slogan has it, and it clearly applies to hi-fi too - "chemists have solutions".
