Texas A&M study finds we think better on our feet, literally

A Texas A&M study found that students with standing desks show greater on-task engagement and academic behavioral engagement, equating to an extra seven minutes of engaged instruction time. Standing desks were also shown to burn more calories than traditional desks, with obese children burning 25% more calories.
