Just leaving this here in case you don’t know: there are also the Framework laptops, which are designed to be modular, upgradable, and have easy to buy replacement parts.
They even sell motherboards, so you can now get a e.g. Intel Core Ultra motherboard for your 3-4 year old laptop.
Of course It’s a bit more expensive than a used 10 year old Thinkpad, but it kind of competes with other high end laptops, and it is cheaper especially when you consider it’s designed to last more
(Not a sponsored post, just glad there is a company that makes such products, and that when I broke a part I could just go to their store and order a replacement instead of searching for serial numbers on random online stores etc like I’ve done before)
Not really a life hack but: folding bicycles are so, so convenient for everyday use (fits in every elevator, fits under your desk at work, fits in public transportation even when it’s crowded, etc)
I really don’t know how they are not a lot more common; you only need a mountain bike if you actually ride on mountain trails often enough. Even non-folding city bicycles are way more comfortable for everyday usage (higher handlebar position and cushiony saddle <3)
