How long can I fool 'em?

I'm really enjoying being at the 2011 Mid American Conference Championships.  I've gotten to see some great swimming and have served the team, alumni and supporters well by taking lots of pictures and video.  With some connections at the meet, I scored a media pass which allowed me deck access to the pool.  During the cool down portions of the meet, I've quickly changed and hopped in for 30 minute swims.  For the time being, I think I've fooled everybody into thinking I'm on a team.  I just wonder how long that type of luck will last me.  In no way have I lied and said I was with a team, I simply jumped in the pool with the rest of the athletes and began swimming.  The honest truth is that I think my suit, goggles, body type and (apparent) fitness level is close enough to these athletes that I don't seem to draw any attention.  I'm 30 years old and apparently I can pass for 22.  I can't imageine that can last much longer, but for the time being, I'm really enjoying it :)
