I would say I've observed enough that I am confident with my con

癌症中心有50+ chemo chairs. Patients come and go and chairs are always full. I stay there 3-4 hours 3 times every 2 weeks. I've been there since Nov. This means I observed at least 100 people every week, 600 in total

Cancer support team, each 10-20 participants meet regularly. Met 3 such groups. Another 30-60

2 Churches, each has a cancer support program with 20-30 participants. That's 40-60

I would say I've observed enough that I am confident with my conclusion.  北美亚裔非主流，不大可能有资金做亚裔调查那我们就自己帮助自己吧
