claim: risk of covid-19 hospitalisation rises exponentially with age , inversely proportional to t-cell production
evidence_1: this mirrors the well studied exponential decline of both thymus volume and t-cell production, which halve every 16 years.", "the strikingly simple inverse relationship between covid-19 risk and thymic t-cell output reported here begs a mechanistic understanding and suggests that t-cell based therapies may be a promising target.", "in addition, incidence of severe disease and mortality due to covid-19 are both higher in men, consistent with the degree to which thymic involution (and the decrease in t-cell production with age) is more severe in men compared to women."
