A couple or three years ago, on one of the "every six months visits" to
the VA med center, we were done, I was getting up [a slightly more than
trivial action at advanced ages] and I mentioned to him that I had this
continuous mild charlie horse in my left calf. Been there for some
time. It really was mild and I wasn't complaining, just mentioned it.
He typed on the computer and then said ... "Go to ultrasound imaging. Go
immediately. Do not pass GO and do not wait for two hundred dollars.
They'll be expecting you." I did and they clapped me in the hospital
and began dripping heparin into me, the clot had relocated to my lungs.
I seem to have recovered although I still use O2 while sleeping and
sitting still watching SF Giants games. The end of every inning is the
7th inning stretch for me now.
If one is active, I doubt one RT airplane trip would cause a problem but
I'm a retired engineer, not a doctor. Sitting at the rig all weekend,
every weekend working 24 and 48 hour contests certainly could.

Hi all,
No, DVT is not, in this context, the rate of change of voltage over time.
But it is about things not changing enough.
I was thinking the other day about how many sequential hours we all spend
sitting on a cross-country flight. This was on my mind because I have one
coming up -- to Dayton, Ohio. Then I thought about an article I read
recently, reminding me how sitting for long periods of time just isn't
good
for human anatomy. They say you need to get up every 20 minutes or so and
walk around, stretch, feed your pets, get the mail, whatever. Anything but
sit for hours on end. Pun intended.
Why? DVT...deep-vein thrombosis. (I hear you saying, "WTF?" But in
fairness, I did put "OT" in the subject line.)
In short, prolonged inactivity can cause DVT and complications thereof.
I'll spare you the details, as I'm not qualified (just Google it), and
I've
never had it myself. Let's just say the consequences can be scary.
Then I thought of ham radio. At times we're at the inert,
four-paws-in-the-air, bleeding edge of the bell curve in terms of sitting.
Not just for hours. For some events it's large fractions of a day.
With renewed awareness I now use nannyware to periodically break me out of
a techno-trance.
Though avoidance of DVT was never a stated goal for our product offerings,
it's a happy coincidence that our portable gear gives some of us another
excuse to get out of our chairs. In hindsight I can see the benefit to our
customers at trade shows: they're more than their share of ageless,
timeless, energetic and athletic.
Anything that encourages movement is in this category, of course, from
high-band HTs to bicycle mobile to climbing your tower.
My advice...keep on truckin'. And thanks for the bandwidth.
73,
Wayne
