Television has never known what to do with grief, which resists narrative: the dramas of grief are largely internal - for the bereaved, it is a chaotic, intense, episodic period, but the chaos is by and large subterranean, and easily appears static to the friendly onlooker who has absorbed the fact of loss and moved on.

To mourn is to wonder at the strangeness that grief is not written all over your face in bruised hieroglyphics. And it's also to feel, quite powerfully, that you're not allowed to descend into the deepest fathom of your grief - that to do so would be taboo somehow.

The importance of heart health became very real for me when my father died of heart disease seven years ago. Having experienced the loss first hand, I am inspired to do everything I can to break the cycle and prevent families from losing loved ones to this preventable disease.

I think maybe even one of the reasons I became an actor was actually to hide. I mean, it sounds paradoxical because, of course, people are standing up in a public place and encouraging other people to look at them. So that's not the conventional definition of hiding.
