I remember thinking that when my mom was 43 she was "so old". She has always aged well. She is 66 now and you wouldnt know it. She maybe looks 55. I am 43 now and I do not know if my perspective is damaged but I do not feel 43, and I do not think I look 43 (not trying to be vain..thats not what I meant). I know having had kids young (first was at age 20) that I am able to grow with them through these technological times. I remember when the internet was nothing more than an inter-office or interuniversity (internal) email-like system called PINE(google it its so lame). I remember when you could really only use a computer in the computer lab at school and the invention of IRC chat rooms-and when someone could send a disgusting picture that would fill the whole screen of everyone's monitor in the computer lab-painfully buffering(imagine a porn picture filling the screens of giant heavy monitor of like 25 people). I remember my first nokia cell phone with the stubby attena(sp). I remember my first texting flip motorola phone. I remember my first blackberry roller ball cell phone and waiting forever for the web page to load...OMG this is totally off track *thanks adhd*. ANYWAY- I am not obsessed with dying young and I do think you can mitigate some of the mental signs of aging by staying plugged in and up to date with technology and your kids.
