你以为国外不卷？我在伦敦见识了英国人如何卷“体能”

The Chinese argument about involution usually assumes competition means academic workload. Having moved from Shanghai to London, Dr Xiaoyun Peng found a city that competes hard, but at fitness. Londoners cycle to work and run after it, in poor weather and on bad surfaces; children climb and sprint in every park, and their parents keep up without looking at their phones. Within a month of arrival her chronic migraines stopped, and her daughter's atopic dermatitis, which had resisted treatment in Shanghai, cleared. She attributes both to daily walking and a regular sleep rhythm rather than to any medical intervention. The essay reframes the claim that life abroad is relaxed: Britain is not competing less, it is competing on a different axis, and physical stamina is what makes a shorter working day possible rather than the reward for it.
