I'm not sure what being older and Asian has do with this? I have a science background and many groups have people from an assortment of different ages/ ethnicities. It would be best for you if do not generalize about specific ages or ethnic groups. Having said that, I am Asian so if there are specific concerns you have I can try to address them. Keep in mind that at least in the US, many Asians are usually pretty adapted to their local culture; age may not correlate with adaptation. I'm 0.5 generation (meaning I was not born but raised in the US) and younger whereas I've worked with people with Asian backgrounds in their 50-60s who were 3rd, 4th, etc. generation.
In terms of what groups to chat with, you will get different perspectives from groups that are mostly scientists vs. groups that are mostly patients. There are many ways to contact researchers if you are a scientist yourself.......like through e-mailing them directly, conferences, specialized research groups, etc.
