will i have alzheimer's disease??

read an article recently, and i realized that i belong to the high-risk group...

- i hurt myself during football last week... according to the article, injuries from contact sports are huge contributors to brain diseases

- i have back pain occasionally... research shows that constant back pain shrinks your brain... loss of grey matter in patients with back pain was equivalent to 10 years of aging...

- my highest academic achievement is university... and i am doing my post-graduate studies now... another study reveals that the higher your level of education, the faster is your memory loss related to alzheimer's... whoa!! almost all my friends are affected by this... =P

darn! what type of articles am i reading these days...?! and i think i shouldn't spend so much time studying....!
