The latest craze, the Ten Year Challenge is making an appearance on everyone's social media.
It's where people are posting side-by-side comparisons of what they looked like a decade ago compared to how they look today.
Some of the contrasts are striking, other people haven't aged a day in ten years.
But for Katie Piper, it was a reminder of how far she's come since 2009.
The 35-year-old uploaded two pictures - and they couldn't be more different.
Picture one showed a badly burned Katie who was suffering in the aftermath of an acid attack that had happened at the hands of an ex-boyfriend in 2008.
She captioned it, ''#10yearchallenge don’t let this challenge create anxiety within you about ageing- it’s an absolute privilege. 1st pic me age 25 year of 2009 in my mums kitchen. 2nd Pic is me age 35 last week in my own kitchen 2019! #lifeisprecious #health#humanbodyisamazing.''
The second photo, from 2019, showed a beautiful and healthy Katie smiling in her own home.
The message that she writes about is important - while many of us are focused on the passing of time in relation to ageing, we must not forget that it also means we have survived and that we are alive.
Her fans showered her in support.
One said, ''This is the best 10 year challenge I’ve seen. Respect.''
While another wrote, ''So true, my favourite saying is ‘Do not fear getting older, it’s a privilege denied to many’.''
This post is so inspiring and has reminded us to remember that your health is your wealth.
