His Holiness suggested it's time for men to withdraw and for women to step forward." In 2015, he said in a BBC interview that if a female succeeded him, "that female must be attractive, otherwise it is not much use," and when asked if he was joking, replied, "No. True!" He followed with a joke about his current success being due to his own appearance. In April 2013, at the Culture of Compassion event in Ebrington Square in Derry, Northern Ireland, the Dalai Lama asserted, stressing the importance of peace of mind: "Warm-heartedness is a key factor for healthy individuals, healthy families and healthy communities [ ... ] Scientists say that a healthy mind is a major factor for a healthy body. If you're serious about your health, think and take most concern for your peace of mind. That's very, very important." On March 2020, the Dalai Lama released a statement published in "Time" magazine entitled "Prayer Is Not Enough. The Dalai Lama on Why We Need to Fight Coronavirus With Compassion". He emphasized "emotional disarmament", meaning seeing things with a clear and realistic perspective, without fear or rage. He stated, "The outbreak of this terrible coronavirus has shown that what happens to one person can soon affect every other being. But it also reminds us that a compassionate or constructive act - whether working in hospitals or just observing social distancing - has the potential to help many". He also said that since the news emerged of COVID-19 in Wuhan, he has been praying for China and the world. He also emphasized that "prayer is not enough", and that the courage of healthcare workers must be combined with empirical science to avert the COVID-19 crisis. In September 2018, speaking at a conference in Sweden's third-largest city, Malmö, home to a large immigrant population, the Dalai Lama said "I think Europe belongs to the Europeans", adding that it should make clear to refugees that "they ultimately should rebuild their own country". Speaking to German reporters in 2016, the Dalai Lama said there are "too many" refugees in Europe, adding that "Europe, for example Germany, cannot become an Arab country." He also said that "Germany is Germany". On 29 May 2011, the Dalai Lama retired from the Central Tibetan Administration. On 24 September 2011, the Dalai Lama issued the following statement concerning his reincarnation: When I am about ninety I will consult the high Lamas of the Tibetan Buddhist traditions, the Tibetan public, and other concerned people who follow Tibetan Buddhism, and re-evaluate whether the institution of the Dalai Lama should continue or not.
