You can lend your support to a worthwhile cause and hopefully encourage others to get involved and help support and create awareness for a specific organisation.
And there are other benefits to being "aff the telly".
For example, I've managed once or twice to sweet talk my way out of a parking ticket in exchange for an autograph, I get ushered into VIP sections of nightclubs without begging the stone-faced bouncer at the door and – my personal favourite –purchasing alcohol.
One supermarket has an over 25s policy and the best way for the cashier to find out if the beer buyer is actually me is to ask for ID. This allows me to tell everyone that I'm constantly being mistaken for someone in their early 20s, and isn't it such a pain to look so incredibly young?
There are, of course, downsides to being well known. For example, when you decide the only way to kill your hangover is to go to a fast food drive through on a Sunday evening wearing a wig, a huge pair of sunglasses and order about £15 worth of food only for the girl on the till to say: "Would you like any salt or sauces Miss McManus?"
Followed by a tweet half an hour later saying: "Was so amazing to see @LadyM_ McManus in my work today looking so cool in a blue wig" – complete with a picture of my car racing out of the car park.
Anyway enough of my sad antics at the weekend and back to my original point of charity work.
I was absolutely delighted to be asked by NHS Western Isles to travel up there this week to start a four-day promotion for the new breast cancer campaign, launched recently by the lovely Elaine C Smith.
It promotes a very simple but very effective message: 'Don't get Scared ... Get Checked.'
I even had the honour of filming an online version of the current advert alerting us all to the signs of breast cancer a few weeks ago.
It's hard to believe that in 2012 we still haven't found a cure for cancer but we must never give up the fight to create awareness of this terrible illness.
And we must do all we can to raise as much money as we can for the ongoing research happening all over the world.
IAm still smiling about the unbelievable climax to the Ryder Cup competition.
I'm not really a regular golf fan but I defy anyone with any sporting passion not to have been off their seats shouting at the telly willing Europe to go on and clinch the cup in what has to be the biggest comeback in recent sporting history.
I honestly don't think I've ever seen a better example of total self-belief like that before, but I think we all know that each and every member of the European team had one thing on there minds...
This one was for Seve Ballesteros – and he would have been so proud.
