I went straight from platform pedals to clipless, at age 57. And I've been a klutz all those years too! Still, thanks to helpful tips and instruction from my sister (aka Trek420) and other TE'ers, I haven't fallen yet. Now in my second clipless season I feel safer clipped in than not, more connected to the bike, more in control, not to mention more efficient pedaling. You'll find lots of tips here and there on TE, stuff like adjusting the pedals to clip as loose as will hold your shoes while pedalling, having a preferred foot to unclip first and always stand on, clipping out that foot when you can see you might need to stop soon (loose gravel ahead, stop sign ahead, that sort of thing), or like practicing clipping in and out while in spin class. You'll quickly get the hang of it, and I'm pretty sure you'll be happy you made the switch.
