Age correlation is primarily linked to expression of coronavirus binding sites (ACE2), which are more prevalent in older people and people with lung damage. ACE2 expression is also affected by genetics and lifestyle factors Reference: Individual variation of the SARS‐CoV‐2 receptor ACE2 gene expression and regulation https://onlinelibrary.wiley.com/doi/full/10.1111/acel.13168 https://onlinelibrary.wiley.com/doi/full/10.1111/acel.13168
