There is, as well, the health aspect of owning your own pool.
There is ample evidence that swimming is one of the best, if not the best, exercise. The great thing is that, other than competitive swimming, it does not feel like exercise.
The benefits of swimming are incredible: it is low-impact, yet builds and maintains muscles (especially as we age); it improves lung capacity, thus processing oxygen much more efficiently and assisting in immunity to illness; it can help reduce stress, both physical and mental; to name a few.
