In the dim and distant past when life’s tempo wasn’t so fast, Grandma used to rock and knit, crochet, tat and baby sit. When the kids were in a jam, they could always call on Gram. But today she’s in the gym exercising to keep slim. She’s checking the web or surfing the net, sending some e-mail or placing a bet. Nothing seems to stop or block her, now that Grandma’s off her rocker.
