Marcus Reed

Marcus Reed spent his early career in enterprise software before a health scare in his mid-thirties sent him down a rabbit hole of wearable devices, continuous glucose monitors, and HRV tracking. He emerged with a clearer picture of his own biology — and a strong opinion that most health technology is being wildly oversold while the genuinely useful tools get buried under the noise.

At Longevity Direct, Marcus brings that skeptical-but-enthusiastic energy to the tech beat. He covers wearables and health apps with real rigour: what the sensors actually measure, where the algorithms are reliable, and where they're extrapolating from thin air. He also writes about AI in healthcare, biohacking (with appropriate caution), thermal therapies like cold water immersion and sauna, environmental health, digital detox strategies, and balance and fall prevention technology — a less glamorous but genuinely important area of longevity tech.

On weekends, Marcus cycles long distances and tests gadgets that his partner describes as "completely unnecessary." He considers this fair feedback and documents his findings anyway.
