Being an MP is the best part-time job in Britain, and possibly the world.
Decent salary.
Huge expenses
Subsidised bars and restaurants.
Long holidays.
Amazing pension.
Much of the work is dealing with constituents' problems. This is largely an administrative task. You send a copy of their grievance to the relevant authority with a cover letter and then send the response back to the punter. Any Town Hall clerk with a year's experience could do that.
Committee work? Mainly mumbling agreement or disagreement. If there's something you really object to, you can say so.
Chamber work? Mainly voting in accordance with the Whips' instructions and shouting 'hear hear'. You can, of course, catch the Speaker's eye from time to time and make a speech or ask a question, but no one expects you to be Cicero. Certainly not in this day and age when most of them can barely frame a coherent paragraph.
When I was 40 I could have done all that without breaking sweat. Talk about a 'Bobby's job.'
