I started EQ when it was on the little black disc and only on MS-DOS, no Windows. LOL I stopped at EQ7. It does everything I use it for, which the last few years has been converting patterns to paper piecing. I agree that the mind has to be used and challenged no matter how old you are. Also I think getting out and doing things is important too. I know one day I won't be able to get in my car and go where I want so I'm doing it now. I take day trips and weekend trips to what interests me, mostly quilt shows. DH is always invited of course but him not going doesn't stop me. I go alone. It really makes a difference to be excited and have expectations of adventure.
