Viruses are small. Like, really really tiny.
If a cold virus was actually as large as my perfect replica in the image below (accurate in every detail, except for the eyes. And the fur. And the colour) the equivalent person would be about 9000km tall, with nostrils about 50km wide.

I've had a missile blow up next to my airplane, been shot at dozens of times by anti-aircraft fire, and launched into orbit — all for my country. I never thought I'd see a President call for my execution.
Trump doesn’t understand the Constitution, and we're all less safe for it.

This is a dark and dangerous path.
The government has said it won’t be rushed, and I sincerely hope this means that Ministers will reject any EHRC guidance that further harms trans people.
Parliament should instead make clear in legislation that “single-sex spaces” are to be trans-inclusive.

Trump suggests Khashoggi had it coming: "You're mentioning someone that was extremely controversial. A lot of people didn't like that gentleman that you're talking about. Whether you like him or didn't like him, things happen. But he knew nothing about it. You don't have to embarrass our guest."
