do you know anyone with colorblindness?
Yes, we had a co-worker who was colorblind. It is very strange and unfortunate thing that can happen to a human being
really interesting. did you witness/experience anything with them that affected their daily living negatively? 
Not really. He was behaving normally as he would. By the way, are you knowledgeable about brain disease called dementia
that's always nice to hear! & I mean...I'm not an expert but I knew a thing or two about it. Why do you bring it up?
I was just curious if you had encountered anybody with such disease in your life? And how those people typically behave overall?
no I haven't. but i've seen videos on youtube and this population is veryyyy forgetful. it's actually alot like alzheimers. they forget things from one day to the next, your brain slowly starts deteriorating and eventually your daily living skills diminish. :/ 
yes indeed. It is much like Alzheimer's, forgetting about recent events. I feel pity for those people and it just melts my heart seeing them in such conditions
