What are you slowly realizing as you get older?

Also not really a new realization nor a surprising take, but how fast life really passes you by. One of my pup's 18 now and struggling a bit, and my mom's been bed-ridden with ALS. It really made me think back how just a short while ago, both of them were getting slightly worse and worse health-wise. Anyway, that's just to say to cherish the little moments in life, and how a lot of the things we worry and argue about are actually meaningless and minor in the grand scheme of things.
