Dear Rhys,
The weight is probably less of a problem than the size. I would imagine that
walking would be quite difficult even if you were able to provide the
necessary support.
I would suggest that for the short term, he should use a wheelchair with a
sling underneath the seat. If that is unacceptable, then you might be able
to modify a backpack frame with straps and a sling to hold them. 34Kg would
be less than the standard carry weight for a military backpack. In the USA
the typical pack weight is nearly 50Kg.
Of course from an RP standpoint, removing them altogether and replacing them
with prosthetic implants would make more sense. You could scan them and
scale them down to normal size and RP replacement ones.

Dear RMPL
I need some help.
I've been asked for some advice on a design problem and I'm having some
trouble thinking of ideas.
A prosthetist/orthotist friend of mine saw a patient yesterday with swollen
testicles. When the patient arrived at the hospital they wieghed one hundred
and forty pounds (64Kg) but since removing a lot of the fluid they've
managed to bring the weight down to 84lb (34Kg).
Now the pateient seems fairly comfortable with this, but as you can imagine,
he's having trouble getting about. These big boys are 1.5metres in
circumference, apparently they look like a very large ham!
My orthotist friend has to design some kind of harness to support these
fellas so the patient can get around.
We thought of a carrier bag and braces (suspenders for all you Yanks) but
then 84lb is a hell of a lot of weight on the shoulders.
Next idea was a supermarket trolley, it could even be sponsered by Walmart
or something!
If anyone has any good ideas, I look forward to hearing them
Cheers
Rhys
