John Williams has a pacemaker!

Pacemakers are also not the large devices they once were and some even have an internal defibulator unit, depending on the model and the person's medical situation. People are now living much, much longer with these things. Its no longer a "Itll give them two more years" but more like "This will give them AT LEAST another eight to ten years" (and even then, people are so closely monitored they can often tell when the unit needs to be updated/replaced/etc).

But this only really applies to iPacemakers.

The PonoMakers, for example, are much faultier.
