I figure I have 20 yrs at best left. No crystal ball here, but going on averages with consideration on health factors. I wear simple things and couldn’t care much for anything formal. Durable is important though. I stocked up on jeans, pocketed tee shirts, socks, underware and socks to make it that long. I also got several pairs of sketcher sneakers and a couple pair of good Justin boots. I’m more worried an economic collapse where getting supplies may be difficult than my lifespan. With the shape the world is in right now I’m glad I’m nearer the end of my life than at the beginning.
