@@ -9,16 +9,11 @@ Hello there, I'm John Kilpatrick!
 I'm a Physics PhD student and amatuer software developer, based in Exeter, 🇬🇧.
 I'm looking into how we can use a [fancy mirror array](//en.wikipedia.org/wiki/Digital_micromirror_device) that you might find inside a computer projector to turn things from translucent into transparent.
 
-I am currently president of [Exeter Photonics](//twitter.com/exeterphotonics), which runs some outreach activities.
-
 I graduated from the University of Exeter in 2020 with a master's degree in Physics with study in New Zealand.
 
-Things I'm excited about at the moment:
-
-- Building performant and accessible websites
-- Cross-platform design systems
-- Great developer experience without sacrificing user experience
-- Hackathons that are inclusive and don't burn you out
+When I'm  you can find me hiking and camping in the beautiful Dartmoor countryside or chatting with friends over a cup of coffee.
+I love being close to nature and discovering new places.
 
-When I'm not staring at my computer, I like to get outside for a walk or bike ride.
-Whilst I am not particularly strong, I also enjoy olympic-style weightlifting.
+I'm also passionate about science outreach and connecting with others, so feel free to reach out and say hi!
+I hope you find something interesting or useful here.
+Feel free to [get in touch](/contact) if you have any questions or feedback.
