Most of my biohacking equipment lives in a drawer: a pulse oximeter, some red-light glasses, and a cheap EEG headband I rarely use. The real game-changer has been a continuous glucose monitor, even though it feels weird wearing a tiny sensor on your arm. I also swear by my cold-plunge setup in the garage — just a stock tank and a pump, nothing fancy. You don't need thousand-dollar gadgets; start with one metric and build from there.
