  In light of recently revised observational measurements of the radius and
spectroscopic parameters of the extremely old and metal-poor Gaia benchmark
star HD 140283 -- also known as the Methuselah star due to prior suggestions
that its age is in tension with the age of the Universe -- we present new, best
estimates for the star's mass and age from stellar modeling. These are derived
using 1D stellar evolutionary tracks computed with MESA and the most up-to-date
measurements from CHARA interferometry. Excluding modeling variance from the
uncertainties, we report a mass of $0.809 \pm 0.001 M_{\odot}$ and an age of
$12.01 \pm 0.05$ Gyr ($1 \sigma$). When dominant sources of modeling
uncertainty are taken into account, we report $0.81 \pm 0.05 M_{\odot}$ and $12
\pm 0.5$ Gyr, respectively. These results are consistent with recent
literature, and the best-fitting age is not in conflict with the currently
accepted age of the universe ($13.5$ Gyr; arXiv:1303.5089 [astro-ph.CO]).
