It creeps up on you, often disguised as wisdom or practical efficiency. One minute you're scoffing at sensible footwear, the next you're meticulously organizing the garage by expiration date. Before you know it, the metamorphosis is complete.

1. You start saying things like, "They don't make 'em like they used to," about everything from toasters to television shows. Never mind that "they" often refers to the same company, just with a new model.

2. You find yourself genuinely excited about a new type of ergonomic kitchen gadget. Bonus points if it promises to "save your back" or "simplify meal prep," even if meal prep currently consists of opening a bag of chips.

3. Your primary concern when looking at a new piece of furniture isn't its style or comfort, but how difficult it will be to clean. Suddenly, stain-resistant fabric is more appealing than a velvet chaise lounge.

4. You begin stockpiling mundane household items "just in case." A cabinet full of extra batteries for devices you don't even own yet becomes a point of quiet pride.

5. You develop an intense, almost spiritual connection to the thermostat. Any unauthorized adjustment becomes a personal affront, complete with dramatic sighs and mumbled calculations about the electric bill.

6. You start lecturing strangers (or anyone within earshot) about the importance of proper posture or the declining quality of public restroom hand soap. Your unsolicited advice becomes your superpower.

7. You initiate a detailed, multi-week project to organize the "junk drawer," only to find it's still 90% mystery keys and expired coupons. The process, however, was "cathartic."

8. You catch yourself humming the theme song to a syndicated daytime game show from the 80s, despite never having watched it as a child. It just... entered your subconscious.

9. You proudly show off your perfectly manicured lawn to your adult children, only for them to point out it's actually the neighbor's lawn you've been meticulously tending for weeks. "Well, someone had to do it!" you exclaim, watering an entirely different shrub.
