Summary

The subjective experience of time accelerating with age is explored through the "logtime hypothesis." The author, in their mid-40s, notes this phenomenon, observing that years pass much faster than before. This hypothesis posits that each new year feels shorter because its duration is measured against the total time already lived; for instance, a year represents 10% of a 10-year-old's life but only 2% of a 50-year-old's. Consequently, periods like 10–20, 20–40, and 40–80 years old should subjectively feel about the same length. The concept draws parallels to the Weber-Fechner law, which describes logarithmic perception in senses like loudness and brightness. The article suggests counting life in "octaves" (e.g., 1–2, 2–4, 4–8 years) to better align with this logarithmic perception, explaining why childhood summers feel endless and early memories are often absent.

Key takeaway

For individuals reflecting on their life's progression, understanding the logarithmic nature of time perception can reframe how you view past and future periods. If you find years passing faster, recognize this is a common subjective experience, not a personal failing. Consider adopting a "life in octaves" perspective to appreciate different life stages more equitably, potentially altering how you plan or value your time.

Key insights

The subjective perception of time accelerates logarithmically with age, making years feel progressively shorter.

Principles

• Time perception is logarithmic, not linear.
• Each year's subjective length shrinks proportionally.
• Weber-Fechner law applies to time perception.

In practice

• Consider life in "octaves" (age doubling).
• Reframe childhood memories' perceived distance.

• Time Perception
