The smoking analogy.....
M8 you hit a cord with that one. The onlyu problem is I am a dumb arse smoker :-) Gave up for a number of years, but started back on the weed......I guess that suggests something about my intelligence ..... or lack thereof!!!!
On a serious note - Appreciated the message behind your post, sounds like you question your past decisions but the other way around from my circumstances.....
No doubt about it ....as humans we are all good at questioning ****...dont know whether it does any of us much good at times. :-)
