Don't Grow Older Than 255 Or Else It Will Overflow

Someone's birthday cake just demonstrated the classic unsigned 8-bit integer overflow problem. They're celebrating their "17th" birthday, but with 256 candles arranged in binary format (well, sort of). The joke? If you store age as an unsigned byte (0-255), hitting 256 wraps you back to 0. So technically, they just became a newborn again.

The candles are arranged in what looks like binary representation: 8 candles for 8 bits. Two are lit (representing 1s) and the rest are unlit (representing 0s). The person who made this cake either has a computer science degree or really wanted to avoid buying 256 individual candles. Smart optimization if you ask me—O(1) space complexity instead of O(n).

Pro tip: Always use a 64-bit integer for age storage. You'll be safe until someone turns 18,446,744,073,709,551,616 years old, at which point integer overflow is the least of humanity's concerns.
