My kidneys are about 25 years ahead of schedule

According to my kidney specialist, all humans lose 1% of their kidney function per year after the age of 40. By her calculations, my kidneys are about 25 years ahead of that schedule.

(So where my kidney function should naturally be in the year 2041, that’s where it is in 2016.)

I always was ahead of my time. Or behind. Rarely on time. :)
