Are introverts shorter-lived than extroverts?
Literal
Introverted people [topic-は] extroverted people [than-より] short-lived?
A pop-science headline-style question. 内気 ('shy, introverted') and 外向的 ('extroverted,' literally 'outward-facing') are a common contrasting pair in Japanese psychology vocabulary. 短命 ('short-lived,' 'having a short life') is a compound of 短 ('short') + 命 ('life'). The question is headlined: it lacks a question particle (か) or copula (だ) — it just ends with a question mark. This is headline-ese: terse, particle-reduced, punctuation-dependent.
