Best of Boston

You already know the New England Aquarium is a magnificent field-trip destination, but did you also know it’s the city’s most exclusive senior-living community? The evidence: In March, the storied nonprofit announced a brand-new “retirement home” island for its geriatric penguins, complete with orthopedic mats, ramps, and acupuncture treatments. More recently, harbor-seal half-sisters Amelia and Trumpet turned 40, surpassing their life expectancies by an astonishing 15 years. Premium healthcare and waterfront real estate really do make all the difference.
