医生说他活不到十三岁。这个患早衰症的比利时博主，活到了二十八岁。

First, put this man in front of you.

His name was Michiel Vandeweert. He was Belgian, from Flanders, and he ran a channel online where he filmed his ordinary days.

What he had was progeria, an extremely rare genetic disorder.

The name already tells you the illness: the body’s ageing is drastically accelerated.

Children with it look unremarkable at birth; the ageing usually begins to show around the age of two.

Children his age were getting taller; his body was heading the other way.

To this day, progeria still has no cure.

The life expectancy medical statistics give is somewhere around fifteen.

Michiel was diagnosed very young.

A doctor examined him and gave the family something more specific: he would probably only live to twelve.

Twelve.

Note that the doctor said twelve — shorter still than the statistical fifteen.

A child not yet finished with school, and the length of his entire life had already been settled in a sentence.

That number did not come true.

But Michiel passed twelve, and he was still here.

Eighteen, still here.

Twenty-five, also still here.

In the end, he walked all the way to twenty-eight.

Among all the people in the world still living with progeria, he was one of the oldest.

The doctor said twelve. He walked himself to twenty-eight.

More than that sentence allowed him: a full sixteen years.

So what did he do with those sixteen years?

He ran that channel, updating almost daily, and kept it up for years.

It is worth noting that what he filmed was not his illness.

He filmed what he ate that day, where he went, who came to see him, what the weather was doing outside.

Just a day about as ordinary as a day can be, and then another one.

A lot of viewers followed him for years, and what they were watching was simply one person’s days.

He did not point the camera at his own body, and he did not file a daily report on how much time he had left.

What he recorded was what he had done that day.

This week, Belgium’s public broadcaster ran his obituary.

Twenty-eight.

One last thing, and it is the part people get wrong.

The number the doctor gave is a statistical result worked out from a large number of cases; it is not aimed at any one particular person.

What it describes is a median across a group — not where you will get to.

A probability describes a spread, not an order issued to somebody.

Behind the same median there are people who go a shorter way and people who go a longer one.

And Michiel stood at the longer end.

Michiel never argued with that number, and he did not carry it around on his lips.

He simply got up every day, recorded that day, and then lived another one.

He repeated that for sixteen years.

To put it another way: that judgement drew him a line, and he went on walking for sixteen years past it — sixteen extremely ordinary years of getting up, going out, eating, switching the camera on, finishing the take, going to bed.

Think about it: when someone uses a number to tell you this is as far as you go.

Is that sentence a conclusion, or is it merely a probability?
