The smartphone. No contest—it’s shrunk the world, made everything instant. Maps, calls, cameras, all in your pocket.

Instant access to meds lists, appointment reminders, GPS when you’re lost on the way to a doctor’s office—plus video calls so the doctor can actually see what you’re dealing with.

As a long-distance caregiver, it was a lifeline in my pocket.

Life before? Kinda foggy. What’s yours?
