We knew this was the issue.

By the way, this goes back a century.

Knowing this, we know, for instance, in a famous paper from the 1960s, that one in five professional boxers will get dementia from boxing.

That's been known since the 1960s.

So the idea that this is all new and it's all come out of the blue and lots more work needs to be done before we can make any changes.

That's just ridiculous.

This has been a long standing known problem with repetitive head injury.

And now we need to take action.

No.

My focus has been on rugby because I've done most of my research in that area.

I do think that there is more collision than contact in rugby compared to maybe other sports.

There's no question there's a problem for football in relation to heading the ball.

As you know, in the US now, underage sports have banned heading in younger age groups.

And I think the GAA, in my view, also...

Because rugby has a bigger profile in this area, it tends to hide behind the idea that rugby is a completely different sport.

But we all know, we've seen it on the GAA pitches, severe injuries.

So look, every sport has to take this seriously.

I would say that there needs to be a code that we all sign up to.

It's incredible in Scotland that they've all signed up to this, if in doubt, sit them out code.

And even badminton players have signed up to it, Badminton Association of Scotland.
