Maths, chemistry, physics, biology, ummm… Yeah, everyone should raise a headstone over their brains after university. Only brains, though, unless all else is as dysfunctional.
About the highest level of math that I use these days is basic algebra.
At the age of 64, I still calculate in my head….. how many kids can do that these days?
and one can see that english skills are also lacking here…
Here’s what annoys me – I can still remember commercial jingles word for word that I heard more than 40 years ago. Why can I remember that and not quadratic equations?
