1. Although "that" isn't necessary here, it's better to add it to avoid confusion.
2. The noun form is preferred here.

What a significant finding that is. On the other hand, I believe that exercise, nutritious food, and an overall healthy lifestyle may alleviate the effects. What else did the article say about that?

Researchers looked at these people earned between 1992 and 2004, putting the people into three groups. Those who always earned low wages during this time, those who sometimes did and those who never did. They have meant that a person's hourly rate was lower than two-thirds of the US median wage for that year. So if the median wage was $10 per hour, they were earning less than $6.67 per hour.

1. "looked at these people earned" is incorrect. You are talking about how much they earned, so you have to add this part.
2. You need to put a comma between each item on a list of three or more, including the last two, before the conjunction.
3. "they have meant" is incorrect. You are defining low wages according to the researchers, so you should use this here.
4. You should generally avoid starting sentences with a conjunction. Here, you should use a comma instead.

I see. Thank you for sharing this information with me. I believe you have more to share. Please continue.

This is quite concerning because, between 2004 and 2016 these people will be 63 and older, the researchers found that the low-wage group experienced faster aging of the mind. The minds of long-term low earners aged about a year faster than those who never earned low wages over 10 years.

1. You need to put this non-restrictive clause between commas.
2. These two parts aren't properly linked. To avoid a comma splice (an instance of using a comma to link two independent clauses), you should use a full stop here.
3. "mind" is a bit unnatural here. It's not entirely incorrect, but it's better to use this noun instead.
