Telomere dynamics and lifespan
From the bivariate model, we found individual variation in RTL, the rate
of RTL change, and lifespan. We also found tendencies for RTL and the
rate of RTL change to positively covary with lifespan (\(\sigma\) = 0.04
and 0.02 respectively), but the estimates were small and did not reach
statistical significance, as their 95% credible intervals overlapped
zero (Table 5).
