The British royal travelled to Lesotho last year (15) to film the documentary Prince Harry in Africa about his charity he co-founded in 2006, Sentebale, which provides resources to Lesotho citizens affected by HIV and AIDS.

In the film, the 32-year-old reunites with Mutsu, an African orphan he met 12 years ago and stayed in touch with by writing one another letters. The emotional meeting took place in November, 2015, but earlier this year (16), the two were able to see each other again when Mutsu visited Harry's residence at Kensington Palace for a fundraising concert headlined by Coldplay, according to People.com.

The 32-year-old has been actively working with charities in Africa for several years and he explains he first became interested in helping out when he visited the continent as a young boy.

"I think anybody that I've spoken to who has been to Africa, most of the people get it, and Africa gets them," he says in the ITV documentary. "For me personally, it's an escape. And now, not only have I found that escape, but I've found a way to try and use the name and the position for good."

And Prince Harry insists anyone is able to make a difference.

"If you're me, if you're your Average Joe, if whoever you are, if you can't affect politics and change the big things in the world then just do whatever you can do - whether it's in your local community, your village, your local church - walking down the street, opening a door for an old lady, helping them cross the road," he continues. "Whatever if it is, just do good. Why wouldn't you?"

Prince Harry in Africa airs in the U.K. on Monday (19Dec16).
