Now, I know there are many people who have been turned off the Games because of doping and the debacle with Russia has not been dealt with very well by the International Olympic Committee. You can't really argue that widespread doping over the years has taken the gloss off top international sport.
But the way I view it is that we have to simply expect that and enjoy the competition anyway. That is the only way to watch sport and that is what I will be doing with the Olympic Games.
Get sucked into the action, enjoy it and revel in the on- and off-field action. Deal with any doping scandal when it comes up.
These days the dopers almost always get caught, so if someone has cheated they will be found out and the medal will be given to the right person.
If it is later revealed that someone has cheated, then separate that from your overall enjoyment.
The athletic prowess on show is amazing - so sit back and enjoy it.
