Accountancy/Finance workers

[Lanesra]

For any one who works in accountantcy or finance...what would you say are the main advantages and disadvantages of working in your profession as I would love to pursue this as a future career?
Do you think this profession is at a demand and that there are many vacancies and what do you predict for those working in this profession (if you know what I mean)?
Where would be best to work in this sector London, outside London or abroad?
Thanks
