Pott found an association between exposure to soot and a high incidence of scrotal skin cancer in chimney sweeps. This cancer is now known as Pott's or chimney sweep cancer.

Coal contains trace amounts of naturally-occurring radioactive elements. The process of burning coal at coal-fired power plants, called combustion, creates wastes that contain small amounts of naturally-occurring radioactive material (NORM).

Fly ash particles (a major component of coal ash) can become lodged in the deepest part of your lungs, where they trigger asthma, inflammation and immunological reactions.
Over 70 former professional rugby players are preparing for legal action against the sport’s governing bodies according to this report.

The group litigation seems to be in its early stages, but World Rugby & Unions will be starting to get twitchy.

THREAD on the key issues 👇🏼


1) Duty of care

Do the governing bodies (World Rugby, RFU, WRU etc) owe players a duty of care in respect of their health and safety? The answer is almost certainly yes (see for example Watson v BBBoC).

2) Breach of duty

Have the governing bodies breached this duty? This is the first of the major hurdles for any litigation.

The question is essentially whether they acted reasonably in the circumstances.

Did they know about the dangers of concussion and fail to act?

Or should they have done more to discover the dangers of concussion but failed to do so?

The NFL case was based on the fact that the NFL knew of the dangers and covered them up. I’d suggest that’s unlikely here. However, it may be that WR/Unions should have done more sooner.

Much will depend upon the state of medical/scientific understanding of concussion at the relevant times.

For example, in the early 80s it may be that there was no indication that concussion might cause long-term complications but, by the early 2000s, there was.
#Kanishka I was, the greatest, and certainly the most famous, of the #Kushan kings.
He is known, from the combined testimony of the literary, epigraphic, and numismatic sources, to have ruled over an extensive dominion extending from Bihar in the east to #Khorasan

in the west, and from #Khotan in the north to, perhaps, #Konkan in the south.

The dates and findspots of some of the inscriptions of #Kanishka I are interesting:
#Kosam inscription dated year 2,
#Sarnath inscription dated year 3,
#Mathur¹ inscription dated year 4,
#Suivihar inscription dated year 11, and
#Manikiala inscription dated year 18.

Kanishka I, belonged to the Little #Yüeh-chih branch settled in Tibet, entered #India through #Kashmir.
He carved out a principality for himself somewhere in #UttarPradesh, sometime after the death of V’ima #Kadphises.

He then extended his sway towards the west and the northwest.
However, the recently discovered #Rabatak inscription #SurkhKotal shows that he was, in fact, the son and successor of V’ima Kadphises.
Kanishka I attained several military successes in the east.
Belief is a marriage between two functions of mind - emotion and explanation. It associates a feeling of confidence with an idea about how things are or should


Why should we be wary and cautious about our sense of confidence about what we know?

For the same reason Bertrand Russell's (metaphoric anthropomorphic) chicken should have been wary about the benevolent farmer (see quote at end of thread).

Had it conceived alternative theories about the farmer feeding it, it may have acted differently and had a better life outcome.

Although unlike in Russell's chicken metaphor, belief is not necessarily a consequence of the error of induction. Strictly speaking, it never is (again, refer to quote at end thread).

However, when one believes without an accompanying explicit argument (theory), it prevents any possibility for critically questioning the reasons for the belief.
HYPERMOBILE YES! These are exact postures chosen by hypermobile patients with unilateral sacroiliac joint disorder & low back pain on that side. One leg bolsters the other so as to hold up the hemi-pelvis on side the SIJ is subluxing; because it hurts to sit on that buttock.


Another posture that attends unilateral sacroiliac joint disorder in hypermobile people is the Trendelenberg posture. This is to sit flexed forward with elbows on both knees. When brought to their attention, many are apologetic, “I know I shouldn’t slouch”.

The Trendelenberg posture is in fact the wisdom of the body finding the most comfortable position; in this seated bent over position the femurs leverage each sacroiliac joint into an anatomical neutral station; so joint ligaments are not stretched.

Standing posture liked in low back pain due to unilateral sacroiliac joint (SIJ) disorder: keep same-side leg straight & slightly flex knee on stable SIJ side; posture that lowers normal hemi-pelvis down & horizontal with loose sagging side. Body likes horizontal pelvis platform

People with sacroiliac joint (SIJ) disorder sleep restlessly like “rotisserie chicken”, but favored sleeping posture is on the non-subluxing-SIJ side; whereby injured loose SIJ floats upward; better if subluxing-SIJ-side leg is thrown up & over husband, dog, or large body pillow.
