    Titanium is awesome, though. Has similar corrosion properties to aluminum (in that it only oxidizes on the surface), is similar in strength to iron/steel, but is only about 60% of the weight iron. So it’s lighter.
    Plus if you mix in molybdenum and I think some nickel, you can have yourself a very long lasting spring that won’t sag like steel springs after several years.
    Main downside is it’s so expensive compared to iron :(








  • I pushed carts at a big box store for a year in my 20’s. Fucking sucked. In an 8 hour shift you could easily walk 20,000+ steps and walk over 10 miles (GPS verified). And you do it no matter the weather. Pouring rain? Out there. Sweltering heat? Out there. -5F and 6" of snow? Out there.
    This work can be brutal, even for a young healthy person, let alone a 90 year old vet.
    The worst part? I was paid the exact same wage as the cashiers who stayed inside the entire time. About $10/hr on average in 2017.
