In many instances, the bigger issue is funding:
Can you afford £80k?
Can you afford not to have an income for 2 years+?
Once flying, can you afford to live on £25k-£30k, especially if you have a training loan + family commitments, in a location that may be countries away from home.
Can you afford to instruct/GA work on £8k/year?
You must know the reality of the industry today, as too many people seem to think that airline flying is still like the BOAC days and that their life will turn out brilliantly if only they were an airline pilot.
