Holes in one most commonly occur on par 3 holes, the shortest distance holes on a standard size golf course. Longer hitters have also accomplished this feat on longer holes, though nearly all par 4 and par 5 holes are too long for golfers to reach in a single shot. While well known outside of golf and often requiring a well hit shot and significant power, holes in one needs also a significant element of luck. As such, they are more common and considered less impressive than other hole accomplishments such as completing a par 5 in two shots (an albatross). As of October 2008, a condor (four under par) hole-in-one on a par 5 hole had been recorded on four occasions, aided by thin air at high altitude, or by cutting the corner on a doglegged or horseshoe-shaped hole.

Pulmonary embolism (PE) is a blockage of an artery in the lungs by a substance that has moved from elsewhere in the body through the bloodstream (embolism). Symptoms of a PE may include shortness of breath, chest pain particularly upon breathing in, and coughing up blood. Symptoms of a blood clot in the leg may also be present such as a red, warm, swollen, and painful leg. Signs of a PE include low blood oxygen levels, rapid breathing, rapid heart rate, and sometimes a mild fever. Severe cases can lead to passing out, abnormally low blood pressure, and sudden death.

- no
- yes

is low blood pressure a sign of pulmonary embolism?

A: yes

The dairy cow will produce large amounts of milk in its lifetime. Production levels peak at around 40 to 60 days after calving. Production declines steadily afterwards until milking is stopped at about 10 months. The cow is ''dried off'' for about sixty days before calving again. Within a 12 to 14-month inter-calving cycle, the milking period is about 305 days or 10 months long. Among many variables, certain breeds produce more milk than others within a range of around 6,800 to 17,000 kg (15,000 to 37,500 lbs) of milk per year. The Holstein Friesian is the main breed of dairy cattle in Australia, and said to have the ''world's highest'' productivity, at 10000L of milk per year. The average for a single dairy cow in the US in 2007 was 9164.4 kg (20,204 lbs) per year, excluding milk consumed by her calves, whereas the same average value for a single cow in Israel was reported in the Philippine press to be 12,240 kg in 2009. High production cows are more difficult to breed at a two-year interval. Many farms take the view that 24 or even 36 month cycles are more appropriate for this type of cow.

The band's road manager for most of their career was Richard 'Biggie' Korn. When the group expanded to its full family membership by 1967, the six siblings ranged in age from 8 to 19. Joined by their mother, Barbara Cowsill (nee Russell), the group inspired the 1970s television show The Partridge Family.
