If you are still concerned that you may be too old, you could try the following as a last resort.

I was reading our Disciplinary Procedure at work yesterday and under the section titled "The Procedure" there is the following bit (my emphasis) -

Stage 3 - Dismissal Or Sanction short of dismissal
If the conduct or performance has failed to improve the worker may suffer demotion, disciplinary transfer, loss of seniority or dismissal.

Now to get to this position you have various options - theft, damage to property, incapacity due to drink or drugs, physical assault, gross insubordination.

Personally I'd probably go for the drink incapacity and then choose the reversal of the ageing process but you might be a kleptomaniac or like hitting people - they presumably put these various options in to cater for various personality types as they are a caring company. It doesn't say that you can choose but I presume that you can pick the options that you want from the list. (As an aside, I did wonder if I got drunk, stole the MDs car, mooned at the clients and hit the person here who really irritates me whether I would get younger that much quicker - I'll let you know if it works)

We are actually looking for a couple of support staff at the moment so if you are interested in a position do get in touch - and as a bonus we have a local folk club that we run where you would get lots of support.
