Dispassionate-Iah asks:

Is the passage of time relative to the size of the organism? i.e. Will smaller organisms experience time passing slower than much larger organisms?
Also, is the passage of time relative to the pace and no. of one's activity?

What do you think?

There is a scaling rule-of-thumb for mammals that they live about 1.5 billion heartbeats.
- A shrew has a heart rates over 1000 beats per minute, while whales go as low as 8 beats per minute
- Humans currently live 3 billion heartbeats, but take away hospitals, aged pensions and antibiotics, and a billion is about right for the middle ages.

On the other hand, the circadian rhythm built into bacteria and elephants (and almost everything in-between) is set to just over 24 hours in all cases.

No time is time for big things and little things.

However for amusement not being totally serious as you get older and the length of life you have left reduces, time goes faster.
A small child with a long life in front of it perceives time going buy very slowly.

ie time ticks faster the shorter time you have to live

Take this with a pinch of salt, but I would say no. Time waits for no one, it has a 'flow'. Different creatures have for example different response times. A fly can react a lot faster than a human but that's about reaction times. Your local time as in you checking your wristwatch is perfectly adapted to your life time, and that goes for a fly too.

Yes, a small orgasm has a short duration and a big orgasm has a longer or multiple durations.

The basic physical time is the same for everyone on Earth (the relativity of time may be neglected on Earth) but the actual biological time related to the brain activity, often called the suggestive time, is probably different among different species having a brain. Humans are slower because they process much more information than a squirrel. Speed is more important for squirrels. Squirrels live a short but condensed life. When you are older, time appears faster because you have more knowledge to process and maybe the part of the brain used as a clock changes and slows down relative to the real physical time. Everybody seems to get this effect as they age. Over the years, I have experienced a major change in my suggestive time since the earliest time I can remember.

[Hayseed]

When you get older, the velocity of time is the only velocity of interest.  The increase in the rate is strong evidence for all who experience it. I have never seen it so fast.

A deniable apparency. 

[CPT ArkAngel]

Yes, it is probably just a matter of perspective. A newborn baby who feels hunger, just feels hunger.

Steve Taylor (Making Time) has a fairly thorough look at psychological time. He identifies five “laws of psychological time”, as follows:

1. Time speeds up as we get older.
2. Time slows down when we are exposed to new experiences and environments.
3. Time passes quickly in states of absorption.
4. Time passes slowly in states of non-absorption.
5. Time often passes slowly, or stops altogether, in situations where the ‘conscious mind’ or normal ego is in     
     abeyance.

He also identifies “….two basic ‘relativities’ of psychological time …” as follows:

1. The speed of time is relative to the amount of information we absorb and process.  The more information
         there is, the slower time passes.                       
2.  The speed of time is relative to how strong and separate our ego is.  The weaker the structure is (e.g. 
                during early childhood, Zone experiences, higher states of consciousness), the slower time passes.

The most obvious factor in Law 1 is that as we age, each year is a smaller % of our experienced life; but, if I remember correctly, Taylor considers other factors, as well.
