I'm just wondering if anyone else has noticed this, but it seems to me as if the slower the person in front of you walks, the more space they seem to take up. Seriously, just try overtaking some snail impersonating moron when walking down the street, it's nearly impossible. They just seem to somehow be in the way, regardless of their actual size.
Of course I have a theory about it but no real supporting evidence. I belive that a human beings velocity is inversly proportional to their effecive volume. Strangly however a stationary human being is not infinite in volume and is, infact, very easy to get past. Other factors seem to alter this as well. The presence of tracksuits upon a person seems to greatly increase their effective volume, as does the presence of a baby, wether walking or within a conveyance of some kind.
Certain environments also seem to alter situation, with the greatest alteration being in shopping markets where the presence of a trolley or basket some how enables the bearer to fill all available space in an isle even when stationary.
This study is an ongoing process and your input on personal observation is greatly appreciated. Especially with a view to creating an equation to express this phenomenon.
