Does this guy know what hes talking about for MDS?

I just happened to come across this guy and he seems to know about MDS, but this video is 10 months old. Is there any thing that has changed since this video was made or is there anything else he should have mentioned. This stuff is still way over my head and since I'm talking with my doctor in 3 days if this guy is legit, my can use what he says to ask my doctor questions. Any input is appreciated.

Hi @twitt1949 I watched the video…nothing’s changed in the 10 months since he posted. The doctor’s legit and you can take the information you learned to ask your doctor questions.
In fact, I was impressed with explanation of MDS on the video, the various types and the treatments. I’ve gone over most of this with you but visuals are so helpful in learning! So this was a great tool. I’m going to suggest this to @asarnesejr to watch as well!

Let me know how your appointment goes this week!

Hi Lori ......Thanks for replying. I've watched it twice and he does make it easier to understand whats going on. He also makes is easier to come up and get questions to ask my doctor. I had a blood draw a couple days ago and talk to my doctor wed.
Lori did I see you had MDS at one time and had BMT? If so, before your BMT was you just feeling weak and tired or were you actually sick and feeling like crap at times? For me if 'm trying to start my lawn more with with a rope (not electric start). Since its the first time starting this spring it was starting hard. I pulled on that rope maybe 8-10 times I had to sit down and take a break. I just couldn't go any more. 15 mins later I could try again. I might be wrong but maybe caused form red blood cells not carrying oxygen to my muscles?
