7 years

A friend recently told me that every person changes every 7 years. That's a very interesting observation, as if from years 1-7 our observations alter our assumptions, altering our beliefs and ideals. I'm sure each of us can look back 7 years ago and say we're a bit different since then, not necessarily in what we hold to be true, but rather in things like: Preferences (music, games, food etc.), Maturity, Goals, the list goes on. But it's a very interesting thought, it keeps all things new and fresh!
