By law, candidates for the US presidency have to meet three requirements: be at least 35 years old, have resided in the country for at least 14 years and be a "natural-born" citizen. Nowhere does the US Constitution mention anything about having to be healthy, and yet that's all anyone seemed to be talking about all week.
As the election enters its final stretch, the candidates’ physical constitutions have become a top trending topic as their age becomes an issue. Donald Trump is 70, Hillary Clinton a comparatively sprightly 68, making them both some of the oldest candidates for president ever. (Ronald Reagan was the oldest president when he was elected in 1980 at 69 years old.)
