Old vs. New

About 3 years ago I bought a great pair jeans from Diesel.  I wore them 5 or 6 days a week for the first 2 years I owned them, and as they started wearing out I cut down to 1 or 2 days a week.   I recently purchased a new and very similar pair of pants.  This first time I put them on, I was very amused to think that my old pair used to look just like them.  I thought it would be fun to do a little side-by-side to see their wonderful aged look. Keep in mind this is all from natural, every day use, no factory distressing, chemicals or intentional damage.  Also, I don't wash them until I absolutely must, usually an annoying spot or unpleasant smell, which takes about 4 months of heavy wear.  

I carry a pen with steel cap that apparently slowly eats away at my right front pocket.  

The back panels, just inside the pockets are usually the first place to go, from rubbing on the seat of my bicycle.  About a year and a half ago I hand stitched patches on the insides to re-enforce the small holes that were starting to come through.

My day to day life has changed a bit in the past year or so, I'm curious how the wear on my pants will be effected by the subtle changes in routine.  I carry a wallet and a smart phone now, and being in a little dryer climate I also carry Burt's Bees in my front pocket, it seems silly, but I know in a few years time I will have lines on my jeans that don't exist on these old pants.
