Tbh I would be scared that my life would be like the film The Butterfly Effect and every time that I went back I would make things worst in present day,I just wouldn't be able to resist telling that young lad playing in Daybrook Station in '72 what and who to avoid in life,but you know what knowing me I would remember years later what I told myself and wonder why I had to avoid it/them and go and find out and end up in exactly the same position or worst,ever seen The Butterfly Effect Frank,I've seen it three times and each time it's had a different ending (true) it's on again on Sunday night on Great Movies,I wonder if there's four different endings?
