22 years to 20 years to Sgt Paper

Yesterday in the shower I went back to 1987 when the world celebrated 20 years to Sgt. Paper,I was such a big fan of John Lennon and the Beatles that time and I used t listen to " The Magical Mystery Tour"- A radio program by Yoav Kotner about the Beatles every day.I remember that "20 years ago" sounded to me so far away ages and ages ago, now it is suddenly looks like yesterday or even few hours ago!
