And this is normal, and nothing to be alarmed about, but rather expected. What is abnormal is the idea that material things are forever and not the transitory things that they are. The Material is Mortal Error.
Unfortunately, we have to get older to realize that not everything will last forever, nor should it. Even things built "forever" will wear out - or become obsolete or outmoded - over time.
The photo above is of our home in Alexandria, Virginia, back in 2004 or so. We spent a lot of money fixing up that house, but it still had some endemic problems. The foundation, resting in Virginia Clay and Marine Clay, was never very good. And the house as cheaply built after WWII on a budget, and it showed its roots on more than one occasion.
We thought about tearing the house apart and starting over - or adding an addition onto the house to bring it up to "the next level" of price structure. Our neighbors, who had a better made house (a more upscale model in the development) took the plunge and built a spectacular showplace. But it did cost a lot of money - in the six figures - to complete.
Our other neighbor decided instead to move to a larger house, rather than try to add on. They sold the house to someone who lived in it a while, then rented it.
In addition to the structural problems (which my neighbor's house also had) there were economic considerations as well. The area had become much more populated since the days when the farmland was plowed up to build these homes (and no one thought that they would ever sell, as it was "too far away" from DC!). The area was now part of a major metropolitan mega-city, and the land was worth far more than the two-bedroom, one-bath house built on the lot. And the lot, being 1/3 of an acre, was deeded as two separate building lots. The day we bought it, we realized that its real value was not as a "home" but as a building site.
This temple was built in the year 400 and is the oldest wooden structure in Japan, perhaps the world. Much of the temple was rebuilt, following massive fires in the years 825, 1350, and 1780. The temple was also rebuilt after a devastating earthquake in 1936.
I own George Washington's original hatchet! The one he chopped down the cherry tree with! It is over 200 years old. Of course, during that time, the handle has been replaced three times, and the head twice, but it is the original hatchet used by George Washington...
