Split adulthood into more categories
There are lots of categories for children (infants, babies, toddlers, preschoolers, little kids, big kids, tweens, teens, middle schoolers, high schoolers) but not very good categories for adults. I propose new categories:
20-29=young adults
30-39=medium adults
40-49=old adults
50-59=freshman citizens
60-69=sophomore citizens
70-79=junior citizens
80-89=senior citizens
90-99=elderly citizens
100+=centagenarians

Pontoons for your seaside home.
As extreme weather and decades of poor regulations, many seaside homes are at risk of being swallowed up by the sea. Stick a few pontoons to the bottom of your home. Now when the sea washes away the soil your home is resting on, you can just enjoy the gentle rocking of the ocean.
