Facebook Post by Singaporean Ken Ng

[QUOTE=Ken Ng] "Today is National Day. But I dont feel any pride at all. Not because I don't love my country. But because of what our country has become. I'm upset at the widening income gap, and the social divide that separates the rich and the poor. The poor that has to beg for assistance yet have to wait for their applications to be approved, while the rich continues to go about their lives seemingly unaffected by the COVID-19 situation  I'm upset at the mass migration of foreigners in our country. Just take a walk at Changi Business Park (it's called Chennai Businesses Park for a reason), or International Business Park (aka India Business Park). Local PMETs are being diaplaced by these trash, and all our gov can do is to tell us to go for skills upgrading? The number of foreigners in singapore as of today (if I remember correctly), stands at about 30-40% of the local population today. What happened to the promises made to put Singaporeans first?

Man in China Lived Until 500 Years Old?

Subject: [Gaia.com] Did This Man Live To Be 256 Years Old? Li Ching-Yuen, a 7-ft tall herbalist and Qigong practitioner, died in 1933. Investigators found birth records attesting that he was born in 1677, making him 256 years old. Li himself said he was born in 1734, which would make him 197 at the time of his death. At age 10, Li began work as an herbalist, foraging for his own wares. He ate a diet of mostly herbs, goji berries, and rice wine. Li claimed he learnt his herb based diet and special Qigong exercises from a 500-year-old man. In 1749, at 71 years old, he joined the Chinese army as a martial arts instructor. According to his obituary, he married 23 times and produced over 200 descendants. When asked about his secret to longevity, he said: "Keep a quiet heart, sit like a tortoise, walk sprightly like a pigeon and sleep like a dog." Li's last words were: "I have done all that I have to do in this world." Link:  https://m.facebook.com/story.php?story_fbi...
