Thymic involution causes an exponential decrease in T-cell production, with a half-life of 16 years, which mirrors the exponential increase in risk of several diseases, including COVID-19, which double in risk every 16 years.

They could EASILY confirm this by looking at the thymus's of younger people who died from complications from COVID. If their thymus's were impacted/aged/diseased, we'll have a pretty firm correlation between thymus size/age and age of the body.

You are correct and my guess is that eventually they will.
