I feel like being healthy makes you happy even if you earn less and work at a mediocre job

If you have all your limbs intact, good eyesight, no herniated discs, and good physical fitness, just being alive feels like happiness. When you work in an enclosed space and step out for a moment to get some fresh air, looking at the scenery with good eyes feels healing. It's also great when exercising.
On the other hand, no matter how much money you have, if you live with a herniated disc, chronic asthma,
and a life where you can't function without thick glasses, you aren't happy;
even the smallest things become irritating and make you angry.
