When you warp in your first blockhead, it starts off 4 blockyears old. If you already have a blockhead, any you warp in will start off 0 blockyears old. Before a blockhead reaches 4 blockyears, other blockheads have to carry them, because they can’t move on their own. When a blockhead dies, it regenerates at the same age it died. Blockheads are weaker, slower, and have less max health and max hunger when they’re children or elderly. When a blockhead reaches 75 blockyears old, it dies of old age, leaving behind a corpse with all of its loot, which eventually rots into a skeleton. A blockhead that died of old age can’t be regenerated, however, it’ll allow you to warp in another one without time crystals. You can eat foods like fish, blueberries, and kale to slow aging, but there’s no way to stop aging, besides disabling it in custom rules. Custom rules also allows you to speed up aging, slow down aging, or even make blockheads live out their whole lives in one day! Children look like normal blockheads but with smaller bodies and slightly bigger head in proportion to their body. A blockheads that’s 4 blockyears old is 1/3 the size on a grown-up. Babies don’t have hair, and they’re wrapped in a blanket instead of normal clothes. Elderly blockheads have faded hair, and they’re slightly bent over. A blockyear is the time it takes for all of the seasons to pass once.
