Tai Chi - please help with my idea for my undergratuate research proposal

Hi all, I am new to this forum.

I am due to start my final year research proposal very soon and have not yet decided on what area to chose.
I am quite keen on the idea of Tai chi, however my knowledge is very limited in this area. I know that QOL, falls prevention and osteoporosis has been researched a fair bit. My ideas so far for my proposal are Tai chi on weight loss, diabetes &/or peripheral neuropathy or COPD.

Please let me know if anyone has any other ideas or comments on my ideas. Any input appreciated. Thanks in advanced. :)
