This is what I eat for lunch everyday. How long will I live?

everyone will live forever in complete happiness after the technological singularity

Unfortunately long enough to make a thread.

100 years, easy

Depends on what else you're eating, OP. I think an otherwise sensible diet could sustain one of these per day more or less indefinitely. If that is all you eat every day then I would say you probably have only a few weeks before serious nutritional deficiencies set in and a few months before death is likely.

For a 25-year-old male of average height and weight with generally good health, surviving solely on a single sandwich per day composed of two slices of white bread, one tablespoon of peanut butter, and approximately 10 Doritos brand tortilla chips would lead to severe malnutrition and potentially life-threatening consequences. Here's a detailed timeline of the symptoms that might arise from this inadequate diet:

Week 1-2:

Feeling of hunger and fatigue due to insufficient caloric intake.
Potential vitamin and mineral deficiencies may start to manifest, such as fatigue, weakness, and irritability.

Week 3-4:

Significant weight loss due to the body's need to break down muscle tissue for energy.
Potential signs of protein deficiency, such as muscle wasting, weakened immune system, and impaired wound healing.
Vitamin and mineral deficiencies may become more pronounced, leading to symptoms like brittle nails, dry skin, and poor night vision (vitamin A deficiency).

Week 5-8:

Severe caloric and nutrient deficiencies, leading to substantial weight loss and muscle wasting.
Potential for nutrient deficiency diseases like scurvy (vitamin C deficiency), beriberi (thiamine deficiency), and pellagra (niacin deficiency).
Increased susceptibility to infections due to a compromised immune system.
Potential for organ damage, especially to the heart, kidneys, and liver.

Week 9-12:

Extreme weight loss and muscle wasting, putting the body into a state of starvation.
Potential for organ failure, particularly of the heart and kidneys.
Increased risk of serious infections and illnesses due to a severely compromised immune system.
Potential for neurological problems, including confusion, memory loss, and impaired cognitive function.

Beyond 12 weeks:

Risk of life-threatening complications, such as heart failure, kidney failure, and severe infections.
Potential for coma and death if the inadequate diet persists.
