Normalized posterior distributions for age based on isochrones, measured mass, and photometry of V343 Nor Aa/Ab and GJ 3305 A/B. When the measurement touches the main sequence, the uniform age prior favors large ages, but a young age is the clear best fit for V343 Nor Ab, GJ 3305 A, and GJ 3305 B, despite the tail at older ages.
