Excuse me, but could you elaborate on the rarity of PSP? Are you referring to the PlayStation Portable, a handheld gaming console, or perhaps a different acronym entirely? If it's the former, PSPs were once widely available but may now be considered somewhat rare due to their discontinuation and the passage of time. However, if you're asking about a specific type of digital asset, cryptocurrency, or financial instrument labeled "PSP," I'd need more context to accurately assess its rarity. Could you please clarify which PSP you're referring to, and what factors might contribute to its scarcity?

    Eye movement disorders are unique to PSP, with patients losing control over their eye movements, leading to difficulties in reading, writing, and even walking.
