This site's three named customer quotes span a specific age range — 46, 52 and 58 — worth reading that range as one data point about who this site is speaking to.
A 46-to-58 range points toward a middle-aged audience specifically, rather than younger adults or seniors — worth noting if you fall well outside that range when weighing how representative these quotes are of your own situation.
This site is direct elsewhere that individual experiences shared by customers are not clinical results and not typical of everyone — worth reading the age range as context, not as a stated eligibility requirement.
