The experiment was conducted to test the effectiveness of one’s ability to balance and walk on a 2x4 platform that is approximately 332cm or 11ft long, while blindfolded.

First we allowed 4 individuals to walk the 2x4 without a…

Medium and large VSDs that haven't been treated in childhood may cause noticeable symptoms. Babies may have faster breathing and get tired out…
