I was asked, earlier, if I’d mind mentioning The Science Museum’s latest project, Who Am I?, and, as I thought it was a really interesting project I agreed.

You can see all the details here, or on their Facebook page, and they’re on Twitter here.

So what do you need to do? Either leave a comment here, on my blog, or send them a tweet (@sciencemuseum – the hashtag is: #smwhoami) telling them what makes you smile, or, if you’d like, your earliest memory.

I’ll tell you what makes me smile: the smell of wood smoke.

Over to you!
