The Greatest News on Earth

Scientific evidence has shown that neurons (brain cells) can rewire and change patterns throughout your lifetime as a result of your experiences and how you think about them. So your thoughts affect the physiology of your brain and the physiology affects your thoughts.

Think about sex for a minute. That's okay, I'll wait. Once you get an inkling, a whole cascade of hormones are let loose in your body to get you ready to cha-cha. Sometimes it's the other way around; the hormones take the lead and you're not even thinking about anything. (See men who suddenly get erections in elevators).

When your mind changes, your brain changes and because our brains are so malleable, the sky's the limit.

I remind you that I got into Oxford in my 50s even though I failed to get a diploma from Busy Beaver nursery school (look it up, that was the actual name) proving really anything is possible.

But it takes time to alter your habits of thinking; it won't happen with a weekend workshop on 'How to Tickle Your Inner Angel'. You can change but only if you make the effort not to do the same old thing, the same old way, day in and day out.

This is what scientists are giving us in the 21st Century; way beyond what Psychic Madge can read in your palm.

Turns out we're the architects of our own brains. Gloria Gaynor was wrong when she sang, 'I am what I am'. She will have to change those lyrics but it won't be so easy to dance to. What rhymes with neuroplasticity?

I'm on tour until May talking about our brains and how to re-build them with Sane New World.
