A few hundred years ago, an experienced herblorist or apothecary would stock herbs, roots and flowers. Alchemists might have metal filings and vials of aqueous solutions. Now adays, we have teenagers wanting to collect all 118 elements and keep them in display boxes on his wall, with the Periodic Table as a background.
Fortunately, swords are the one thing that do not change over time.
PS: I’ve just spent four, four and a half hours watching the Perfect Kirby series on newgrounds. There are like, a dozen movies in total (from the same author, Pikanjo) and I made sure I watched every single one of them today. And to think, I could have spent that time unproductively, doing calculus or studying economics. Ha!
