Most of us wouldn't go within 100 feet of a creepy, old abandoned building, let alone stick around long enough to photograph what's behind the creaking doors.
Not Canada-based photographer Freaktography (known to his mum as 'Dave'), who travels around North America tracking down the creepiest abandoned medical institutions he can find.
From crumbling rooms that still contain human specimens to rusty apparatus that's been gathering dust for years, nothing's off limits for our Dave.
While we're all sat at home grunting 'Rather you than me, mate', for the photography series Dave has been busy hitting up more than 20 locations across North America to show the public what lies behind closed doors.
The idea came to him when he considered just how many areas are actually completely off limits to the public in places like hospitals - even more so when the entire building is eventually abandoned.
Dave, based in Burlington, Ontario, said: "Hospitals are always huge, so they are fun to explore and you can literally get lost.
"I hope former staff of these hospitals love to look through my photos and reminisce about their time there.
"Also, you would be surprised at just how much goes to waste when a hospital is left behind - it's always interesting to see what they don't have a use for anymore.
"Lastly, there's the amount of empty space in these huge institutions - it blows my mind that these places can't be utilised for anything else once they are no longer needed for their original purpose."
Dave never reveals the locations of the creepy spots in the hope that they'll be preserved for the next batch of explorers, and usually relies on recommendations through word of mouth or searching online.
Speaking of his most memorable moments, he added: "I once photographed the autopsy room in an abandoned hospital and there were human specimens left inside a small fridge with pieces removed during autopsies - the smell was terrible.
"As long as more cities close old hospitals for newer, more modern facilities, this series will continue."
And he's not the only one brave enough to explore such haunting places.
Back in December, urban explorer Warren Tepper visited the North Staffordshire Royal Infirmary, which was once the biggest hospital in Staffordshire before it closed its doors in 2012.
Along with an operating theatre and mould so bad it just looked like a huge sea of green, Tepper was surprised to find the site still had running water and functioning power - watch the video above to see his full adventure.
Recently, another urban explorer, Bob Thissen, also shared his ultimate top 10 abandoned locations from all over the world - probably for us all to ponder for mere seconds before shaking our heads and going 'Nope', before going to stick the kettle on.
Thissen, 33 - who's from Heerlen, The Netherlands - first started investigating local eerie decaying spots during his teens.
Over the decade or so that followed, he's now visited over 50 countries and thousands of locations, from the abandoned ruins of war-torn hotels to forgotten mansions in the woods and dangerous nuclear fallout zones.
