Just a community for everyone to share artifacts, reconstructions, or replicas for the historically-inclined to admire!
Generally, an artifact should be 100+ years old, but this is a flexible requirement if you find something rare and suitably linked to an era of history, not a strict rule. Anything over 100 is fair game regardless of rarity.
OTHER COMMS IN THE HISTORYVERSE:
To add to this one of the main reasons is telomeres, a piece of dna at the end of chromosomes that doesnt really code for anything but they protect rest of the chromosomes from damage. As cells age and divide they get shorter and if too short the actual important parts start to take damage. For some reason they only regenerate in a small set of cells such as embryonic stem cells.
