"""Solution 16.1.1 — Reading an age

Chapter 16: Handling Failures — Everyday Programming

Bug type: Runtime

The int(raw) call happens *outside* the try, so a non-numeric entry
raises ValueError before the except can catch it and the program
crashes. Move the conversion inside the try so the failing line is
actually protected.

Exercise: ex_16_1_1.py
