In the second part of our series of articles centring around the
topic of longevity, we now discuss in greater detail, the emergence
of geroscience, which is the study of ageing and chronic
age-related diseases as one of the key domains of the longevity
industry.
Associated with the rise of geroscience is the growing use of
consumer genetic tests1 to predict age-related diseases
like cancer2 and Alzheimer's disease3.
Additionally, depending on the genetic test involved, a sample of
one's blood, skin (through a cheek swab or otherwise), amniotic

overseas businesses (e.g.
