What would my life look like if I didn't use any foreign products?

Every aspect of modern life is deeply marked by foreign goods. If you used zero imported products, your day would start without a shirt to wear and end in the dark. A life experiment about who we really are.
Morning Dilemma
The alarm clock was invented in Switzerland, cotton for bedsheets comes from the Americas, and nylon toothbrush bristles are a DuPont patent. Even if you insist on using domestic products, you'll find that many raw materials and technologies still originate overseas.
Dietary Challenges
Tomatoes, potatoes, corn, and chili peppers—staples we take for granted today—are actually foreign species introduced to China only during the Ming and Qing dynasties. Without them, our culinary culture would be unrecognizable.
Think
This thought experiment reveals that culture has never existed in isolation; exchange and integration are the norm of civilizational development.
