Long distance runner here. Never felt nausea after a run. Intense hunger yes, feeling sick no. My ex used to feel sick if she was just late for a meal. I’d never encountered that in somebody before. I just assumed that she was wired up incorrectly like that thing where some people sneeze if they step into bright sunlight.

In the UK where everyone has decent basic health care on average you live 2 years shorter if you own a horse. It’s worse than riding a motorcycle (1 year shorter). It turns out that owning a big animal that will kick you if you look at it funny or throw you off if it gets startled by a packet of crisps in the road isn’t that great for your health.
