The transition matrix B suggests different times inside different closed volumes.
More precisely, time passes more slowly inside larger volumes in proportion to V/A=Lc (V=Volume, A=inner surface and Lc is the so-called characteristic length).

Now does it bother you
to go beyond insanity:
If we assume that the vital processes of life in the description of organic and biochemical chemistry are based on a diffusion mechanism, we should expect larger creatures to live longer.
In other words, we can assign different lifespans to different animals, fish, and birds based on their volume and subcutaneous surface.
Here are some very crude remarks:
i-Animals
*Lifespan of the elephant = 65 years and its Lc=2.5m.
* Lifespan of a horse = 25 years and its Lc = 1.25 m
*Lifetime of an ant less than 1 year and its Lc is about 0.04 m
For the birds
**Lifespan of an eagle = 20 years
and its Lc=1 m
**Lifespan of a duck = 6 years
and its Lc=1/4 m
**Lifespan of a small bird = 2 years
and its Lc=1/10 m
For the fish
*** Lifespan of a whale = 100 years and its Lc = 5 m
Lifespan of an average fish = 5 years and its Lc = 0.25 m
This means that the average lifetime is approximately equal to 20 Lc.
Here I should stop and leave comments for Research portal contributors.
