DUDE I’m glad to hear someone else say it
I’m not 45 but I might as well be for all the arm strength or ability to keep my back straight that I have… 

I was gonna start at 12, then do 25, then 50, then 75, then finally be up to 100, taking each step as I felt ready.  Because everyone doing this is starting to inspire me. 
Ok, I have no excuse anymore… I’ll start, too! 

 Let’s all start at whatever level we’re at and just do it every day. 
When I was a kid that’s how I learned to ride  bmx, just kept at it and eventually could do  more stuff 
 - it’s not safe to ride now with my epilepsy though. :(
