The splash of water on your face, your boat teetering on the edge of getting flipped over, your muscles sore from klapping your kayak partner with your paddle.
If you've ever wanted to test your relationship with a loved one, do a kayak day trip together. Or if you're feeling even braver, do a whole weekend. Two people trying to coordinate their steering while fighting with the currents of Mother Nature is a recipe for all-out war, or an opportunity to band together that will make you closer with your partner.
WATCH: Getting up close to a hippo on a Tanzanian river
I grew up with an uncle that was a rowing fanatic, and spend many summer holidays in Namibia rowing the cold Atlantic ocean. One particular trip will forever be stuck in my brain - he decided one year my brother and I were ready for a big ocean trip from Langstrand to Sandwich Harbour - or somewhere around there. My brother and I were foolishly paired up together - and we have never fought as violently as we did on that trip.
I refused to paddle all the way back when reached what supposed to be the turnaround point, shaking so much I could barely speak from a combination of cold and anger, and vowed never to row with my brother again.
Fast forward many years - he was living in Nelspruit and I went up for a visit and we decided to go canoeing for half a day on the Sabie. I was very hesitant, thinking we're going to fight tooth and nail the whole way thinking about the last time we rowed together, but in the end we didn't even say one bad word to each other, navigating the river in perfect unison.
It's amazing what maturity can do to a relationship - and a little time together on the water.
