What's common to money....and air ?

Plenty if you ask me ! Here's a broad level comparison that seems to hold on many grounds :

- Money is like air, in that it's required to live life. Just like air, if not kept in circulation money is worthless by itself. They are just means to an end.
- Both are of no use to a dead person, nor can they be carried over. No amount of air can save an ailing/dying person; no money has been known to buy happiness.
- When polluted both tend to get "black". Blackened form of either is dangerous !
- The faster you run, the more air you need. Similarly, the faster paced life you lead, more money you spend and vice-versa.
- Montain dwellers lead a good or better life than the plains people, surviving on much less air; People accustomed to the rarified spiritual heights require no more than a minimal amount of money.
- Family people are like swimmers immersed in water, exhausting the supply of air (money) and coming up every now and then for a breath of fresh air ! No matter how many times they come up, they go down again and again thus repeating the cycle.

With some imagination, I'm sure many more can be found...
