What could it possibly be like to be old? The stooped shuffle, the halting speech, the dimming senses.

An exhibit opening on Friday at Liberty Science Center in Jersey City answers the question by letting you walk a proverbial mile in your elders’ orthopedic shoes. Slip into the R70i Age Suit, a robotic contraption complete with “augmented reality” goggles, and suddenly you are 85.

It is not very pleasant.

An attendant cranks up a fader and your vision dissolves into melty, grayed-out blobs, like a memorably unvivid psychedelic experience. “This is called age-related macular degeneration,” the suit’s inventor, Bran Ferren, said at a preview on Thursday.

More knobs twiddle, and your hearing is subsumed in a fog of tinnitus, muffling and distortion. A dose of echo is added to the sound mix, interrupting your speaking and simulating the effects of aphasia.
