I was never particularly
active, and worked in offices mostly - some general observations:
 | Around the age of 45, one
evening after work, I realised I was "out of breath", just walking to my car.
What I now reckon had happened is:
 | that my blood didn't have
enough oxygen in it (following a particularly slothful day) |
| The first few minutes of
walking had used up the oxygen in my blood |
| And after those few minutes
- I was panting, to get my blood re-oxygenated. |
| I don't know if that is what
happens in reality - but now - I try to not get too slothful, by walking
and exercising, whenever I can. (Update!! Update!! 24th
Jan, 2003 - had a check-up recently, and the Doc says "WRONG!!". The body
makes sure there is always enough oxygen in the blood AND, that oxygenated
blood (bright red in colour) gets pumped round the body and as the oxygen is
used/removed from the blood - the blood becomes darker/blacker in colour. So I
still reckon I'm on the right track (relating breathlessness to oxygenated
blood), but now revise my theory to encompass "length" rather than "volume".
Meaning that the old theory reckoned there may have been only 55% (volume) of
oxygen in the blood, which was not enough for a fast-start which needed 95% -
so I got breathless. Whereas now I reckon the oxygenated blood has to travel
55 feet for a fast-start, but because I've been slothful there is only enough
oxygen to travel 32 feet.) |

| Palpitations of the heart - I
reckon these occur when:
| You have been at an
unrecognisable level of fitness - lets say "fairly fit" |
| And you either intentionally
(or not), move to another level - say "very fit" or "not at all fit" |
| Going up or down the
"fitness scale" - I reckon - causes the heart to have to revise" its
operation" |
| And for the first week or so
- at the new fitness level - palpitations will occur, whilst it is trying to
adjust |
