We could be talking about how we don’t value our time (an hour of your life is worth a bit less than a pack of incontinence pads) and how valuable knowing your self-worth is.
But I am, after all, an amateur.
And these are troubled, troubled times.
When talking about the value of a life, we should turn to the Doctor. 
What makes you so sure that your life is worth more than those people out there on the ice?
Is it the money?
The accident of birth that puts you inside the big, fancy house?
Human progress isn’t measured by industry. It’s measured by the value you place on a life.
An unimportant life.
A life without privilege.
The boy who died on the river, that boy’s value is your value.
That’s what defines an age.
That’s what defines a species.The Doctor, Doctor Who, Season 10, Episode 3
 Yes, I made that joke. Yes, I am a nerd.
