There’s a few obvious ones but my best life hack, as a dude, is regarding shaving razors and cream. Those Gillette things in the UK are damn expensive. They got like 4 razors, super fancy. And the cream too. You don’t need it. I bought a massive bag of the classic razors off of Ebay and moved to the classic shaving soap. Lasts me months.
Thanks. I’ll use this as an excuse to fart on the beach: “No, it’s the parrotfish poo”
