Hi folks: I am really bad at introductions. So I'll see what I can do. I am physics/chemistry (mature) student who is still deciding what to do with the future. I have a background in...well, all sorts really: from science technician, to real state agent, to waitress, to bingo moderator, etc etc I finally decided to join because I always seem to end up on this site whenever I have a question and need answers that I can rely on. So I hope I can be of help to others as much as you guys are helpful to me.
