Should I replace leathers after 10 years?

[SVS]

I've been using the same leather pants for over a decade. Should I replace them? I've cleaned and fed the leather every year. The leathers still look and feel remarkably good, but how long does stitching remain strong?

LOL

I'm not admitting whether the waist elastic has stretched ...

Yes: [boffin]Skin cells only live 2-3 weeks, so they are continually being replaced.[/boffin]

I'm also uncertain how long seam burst strength remains reliable in stitching. However, I think I'll give my leathers a clean and feed for another year's use. Leathers ain't cheap to replace.
