I know age can be a big barrier, but at 43 you are still a stud, and have at least 22 years flying subject to health or course. Grant it the older you go, you may have to 'pay a little more' to get the licenses you want, such as the old swear word here......
'Paying for your own type rating' ....ahh sorry I said it, dont everyone pile into me, but its a fact of life for some.
Go for it, dont let anyone or thing stand in your way and take a leaf out of my motto;
One life....live it
Good Luck, everyone deserves it
