As I’m still a relative newbie I love reading the back issues of T-mag. I see that this topic was discussed a lot last year but it’s new and worrying to me! I’m a student living in halls and eat lots and lots of tuna (5cans a day!!) It’s skipjack tuna canned in springwater. Is this going to do me some serious neurological damage? I,ve got exams in two weeks… I can’t afford any memory loss
