Pizza
The pizza represents one of humanity's most democratised culinary achievements. Available on virtually every inhabited continent, it can be procured within minutes across most urban centres. The average Briton lives within 1.2 miles of a pizza establishment. Frozen varieties occupy dedicated sections in supermarkets worldwide. Home preparation requires only basic ingredients: flour, water, yeast, tomatoes, and cheese. The barrier to entry is remarkably low, with children as young as five capable of producing serviceable specimens with minimal supervision.
Delivery infrastructure has evolved to ensure pizza reaches consumers with unprecedented efficiency. Mobile applications track each pizza's journey from oven to doorstep. The technology exists to receive a pizza within thirty minutes of the initial craving, a feat of logistics that would have astounded our ancestors.
Mars
Mars presents considerable accessibility challenges. Located between 54.6 million and 401 million kilometres from Earth depending on orbital positions, the planet requires a minimum seven-month journey using current propulsion technology. No commercial flights are available. No human has yet set foot upon its surface. The total number of successful Mars landings stands at fewer than ten, all unmanned.
Viewing Mars requires either a clear night sky and functional eyesight, or access to telescopic equipment. The planet appears as a reddish dot to the naked eye, visible for portions of the year when orbital mechanics permit. Virtual exploration via rover imagery offers the closest approximation to a Mars visit currently available to the general public.
