Einstein's *Special* Theory of Relativity

Today we learned about relativity, time dilation and length contraction. It just so happened that today was one of the slowest days I've ever been through; triple economics, double maths and physics. Economics was the primary cause - I think I actually dozed off within 10 minutes into the lesson. The topic we're doing now is unbelievably boring. Anyway, it also gave me time to think - I'm hoping that relativity is actually the reason why I am so slow at doing everything. Just this week, it's been shown that I walk, swim, clap and text slow. So, how likely is it that relative to everyone else I'm moving at near the speed of light? 
This is kind of where my argument fails.
Ah, also, I do feel a little bit sad (as discussed in physics today) that I am actually discussing relativity and what not in a blog post.
