We don't have to follow it blindly, but yes, throwing certain inhibitions to the wind is good. As we get to the age where we no longer dress to comform to fashion I'm all for a bit of eccentricity.
I was walking along a low wall following GS3 earlier this week because I thought it looked like fun and it was a long, long time ago when I was a child, since I did it. I didn't care who was watching me.
And kicking up the autumn leaves with GS1 on the way back from school, and jumping in puddles, and singing songs out loud. Children laugh so easily and so often, us oldies need to get the laughter and fun cells ticking over a bit more.
But if you don't want to do anything then that's fine too.
