Alysa Liu won gold medal in figure skating at the Olympics earlier this week.
She is one of five children born to a single dad, who moved from China to the USA. He decided to have a family in his 40s and used two surrogates. Alysa is the eldest of his children. Three are triplets. He seems to have used a white egg donor and people are speculating that he selected for athleticism.
Lots of discussions about the ethical issues on other sites.
