I’m late 30s. I’ve slowed down a lot since my 20s. Reflexes aren’t anywhere near as sharp, I use to have very quick hands and reflexes. As far as memory, I’m still good at remembering things that I care about but it’s far from the steel trap it use to be. For stuff that’s not things that I care about I have to write it down, I’m still pretty good but I forget stuff now.
I use a version of this, it’s based on the neti pot from india. Completely natural technique and does more than clearing our your sinus. It also stops any post nasal drip, Globus (lump in the throat) and can help with snoring.
