Old and young life

This aged tree is being supported by about twelve wooden posts.  Not having seen the process, I can’t say for sure, but I suspect that these posts came from significantly younger and significantly more numerous trees.

Kill 12 to save 1?

It brings out an interesting discussion about the relative values of lives.  In humans, we tend to value youth over age.  Think of all the stories, books and movies where the old guy gives up his life for the sake of saving a younger person, especially a child.

Whereas with plants, the opposite is often true.  People get enraged when older plants are cut down and replacing the destroyed plants with new ones is often small recompense.

When humans approach extremely old age, it is true that they are revered and extremely valued.   Once a person reaches a “rare old age,” they are given great care and attention.

No comments on whether this is good or bad, just an oblique comment on the interesting reversal of value on aged life between humans and plants.

Neither a pet owner nor farmer, I have not spent much time around animals.  Do you have any thoughts to share about where the value lies with animals?

Mixing Old and New Batteries

Many battery-powered electronic devices come with a warning like this:

BATTERY WARNING:

Do not mix old and new batteries.  Do not mix alkaline, standard (carbon-zinc), or rechargeable (nickel-cadmium) batteries.

One device I noted this warning on was an automatic card-shuffling device. It seemed entirely out of place, since the machine only used ONE nine-volt battery.

Of course, the advice is sound and should generally be followed.  However, in this case I don’t think the warning necessary, as it would be practically impossible to use multiple batteries at once in this device.

According to Duracell, the reason to avoid mixing old and new batteries is that doing so will reduce overall performance and may cause battery leakage or rupture.  If you’re curious, for a more detailed explanation take a visit here.
