Betty Remedios, 63, has a pep in her step as she gets out of the horizontal cylinder in which she’s been getting “intermittent vacuum therapy” in Andheri West. It’s a treatment to boost circulation in the lower body. It involves the user placing their bodies into the cylinder from the waist down, after which a vacuum pump alternates between normal and low air pressure to stimulate blood flow. It’s a technique used especially in sports injuries. More recently, it has gained attention for its ability to accelerate muscle regeneration, and the hope it brings for longevity medicine.

Longevity — it’s a word readers have no doubt been seeing a lot of in the past few days, ever since Zomato founder Deepinder Goyal stepped down as CEO of parent company Eternal on January 21 and left to chase his next passion: health and longevity research.
