But it still takes intense training to be able to hold one's breath for such an extended period of time.

Given China's poor track record in addressing U.S. complaints about intellectual property theft and forced technology transfer, one should not hold one's breath for a further de-escalation in the U.S.-China trade war next year.

When the bridge was mostly used by horse and wagon, couples would stop half-way across to share a kiss. The first wedding on the bridge was celebrated in September 1992 between Charmaine Laffoley and Dana Hunt from Toronto. It is thought by some locals to be good luck to hold one's breath the entire way across while driving.

Sleeping in a more upright position seems to lessen catathrenia (as well as sleep apnea). Performing regular aerobic exercise, where steady breathing is necessary (running, cycling etc.) may lessen catathrenia. Strength exercise, on the other hand, may worsen catathrenia because of the tendency to hold one's breath while exercising. Yoga and/or meditation focused on steady and regular breathing may lessen catathrenia.

The greatest danger is in attempting to hold one's breath before exposure, as the subsequent explosive decompression can damage the lungs. These effects have been confirmed through various accidents (including in very high altitude conditions, outer space and training vacuum chambers). Human skin does not need to be protected from vacuum and is gas-tight by itself. Instead it only needs to be mechanically compressed to retain its normal shape.

Next, the arms should be swung from one side to another in a twisting motion, with each swing to a side counting as one repetition. The slower one moves the arms from side to side, the harder the exercise becomes, working the abdomen that much better. When moving one's arms during the exercise, it is crucial to not stop between repetitions or else one will lose the effect of working the abdomen. Constant breathing in and out during the exercise is important as one should not hold one's breath.

This is especially perilous for high-altitude fighter pilots. It is also why flight attendants instruct passengers, in case of loss of cabin pressure, to apply the oxygen mask to themselves first before helping others; otherwise, one risks losing consciousness. The respiratory centers try to maintain an arterial pressure of 40 mm Hg. With intentional hyperventilation, the content of arterial blood may be lowered to 10–20 mm Hg (the oxygen content of the blood is little affected), and the respiratory drive is diminished. This is why one can hold one's breath longer after hyperventilating than without hyperventilating.

A popular game amongst local children, and some adults, is attempting to hold one's breath for the duration of the journey through the Clyde Tunnel. This is possible due to the short length of the tunnel – a car travelling at the limit takes 57 seconds to pass through, and at off peak times traffic is often flowing at around , resulting in a transit duration of 42 seconds. Success is hampered by snarlups (particularly at the interchange on the north end) slowing traffic. The breath-holding game was the subject of Scottish artist Roderick Buchanan's video Gobstopper, for which he won the Beck's Futures art prize in 2000.

115 Not everyone shared Lalo's view; some audience members equated undemonstrativeness with dullness: Reynaldo Hahn commented, "[Messager] is not a master of the theatre ["chef du théâtre"], being too exclusively musical; he sets too much store by detail without feeling the spirit of the public behind him, and does not understand the variable musical flow that makes one hold one's breath, sigh and wait."Quoted in Wagstaff, pp. 38–39 Nevertheless, Hahn admired Messager as an orchestral conductor: > André Messager is the most French of conductors; I mean that in this art he > embodies sharpness. Grace and clarity are not uniquely French qualities: > they are frequently found among the Italians and even some Germans.

In the absence of central apnea, any sudden drop in oxygen or excess of carbon dioxide, even if small, strongly stimulates the brain's respiratory centers to breathe; the respiratory drive is so strong that even conscious efforts to hold one's breath do not overcome it. In pure central sleep apnea, the brain's respiratory control centers, located in the region of the human brain known as the pre-Botzinger complex, are imbalanced during sleep and fail to give the signal to inhale, causing the individual to miss one or more cycles of breathing. The neurological feedback mechanism that monitors blood levels of carbon dioxide and in turn stimulates respiration fails to react quickly enough to maintain an even respiratory rate, allowing the entire respiratory system to cycle between apnea and hyperpnea, even for a brief time following an awakening during a breathing pause. The sleeper stops breathing for up to two minutes and then starts again.

The Long Gallery at Abingdon Abbey Of the Benedictine Abingdon Abbey there remains a beautiful Perpendicular gateway (common local knowledge, however, is that it was actually rebuilt out of the rubble of the original, and a little cursory examination of the patternation of the stonework will apparently divulge this) and ruins of buildings such as the mainly Early English prior's house, the guest house and other fragments. Other remains from the former abbey include the Unicorn Theatre and Long Gallery, which are still used for plays and functions including an annual craft fair. Abbey Gateway between the Abingdon County Hall Museum and the Guildhall remains a point of local importance. Although it is unclear how far back this tradition dates, some people from families that have lived in the town for generations follow the superstition that in walking under the gateway one should hold one's breath to stop the gargoyles that decorate the gateway from stealing it.
