At what age do we age the most?

You age the most during two major "bursts" of molecular change, around age 44 and again at age 60, when your body's molecules, proteins, and microbes undergo significant, non-linear shifts, affecting metabolism, immune function, and more, rather than a steady decline. These aren't the only times; some research also notes bursts around 34 and 78, but 44 and 60 are prominent periods of accelerated aging.

Are we still in the Iron Age?

Technically, yes, we are still in the "Iron Age" because iron (specifically steel, its alloy) remains the dominant, fundamental metal for tools, machinery, and infrastructure, but archaeologists often mark its historical end with the rise of written history or specific empires like Rome, while some propose new "ages" like the "Silicon Age" or "Plastic Age," acknowledging our shift to new dominant materials and technologies. The traditional Three-Age System (Stone, Bronze, Iron) ends with the Iron Age, but this system struggles to categorize modern complexity. 

What is 50 years of age called?

A person in their 50s, including someone who is 50 years old, is called a quinquagenarian, derived from Latin for "fifty each," while the 50th anniversary or milestone is a semicentennial, often associated with a "golden" theme.

There's no single "hardest age," but many sources point to the 20s and early 30s (roughly 22-42) as a peak period for life challenges, marked by career building, self-discovery, financial stress, relationship uncertainty, and figuring out adult responsibilities, with some identifying age 35 as a specific tough spot due to colliding expectations and realities. However, difficulty is subjective, with some finding teens (identity), 40s (mid-life), or even later years challenging due to physical changes or family crises, though the 20s often feel hardest retrospectively for their intense self-creation pressure.
