You are over the hill, around the bend, up the creek, long gone, elderly, aged, in your dotage, antique, long in the tooth, ancient, dinosaur-ish, post-vintage, senile, feeble, wobbly, toothless & no spring chicken!
Instead of a motorbike I recommend a low-speed rocking chair with seat-belt & roll-bar, a shawl, and a nice bowl of Pablum. Maybe a Lawrence Welk CD on the box, turned down low.
Take my word for it...I started riding in 1957 at age 14.
Still at it and been riding now for...ummm...well, hell, I don't know, a long time.
Should have stopped at age 21 and took up golf. You should take up Checkers!
But...if you just refuse to take my advice, you can't go wrong with a T-Dub!
And at your advanced age it will be the most fun you can have with your clothes on...or off.
Hellz yes, get that bike and ride on OLDMAN...ride on!
And welcome to the forum...you're in the right place.
