I'm not a doctor - so I can't describe flashbacks well - but it is like you're living it again.
My poor mum had a lot of problems with me around that time. I was young but I'd been working for years, so if she asked me to clean my room I'd say, 'You can't tell me what to do after I've worked a 12-hour day.' It gave me a power that no one that age should have.
I don't think anybody would dispute that we're seeing a warming of the Earth.
