The most expensive bacon sandwiches around...
At £2.50 plus per minute training and over £2 per minute hiring there are a lot of interesting pastimes that would be kinder to your bank, your body, your mind and your emotions.
It is an emotional event to fly and we have, wait for the pun... highs and lows naturally as part of the human condition. Ration yourself until you can no longer bear to be a spectator and then immerse yourself again - that's what a lot of people have done successfully unless you cannot afford it.
Have fun in whatever gets you that extra zest for life while you still have useful life left. We are only here once and some of us are not here for all that long (not me I hope but as I write this I am surrounded by friends and relations with lung cancer, leukaemia and brain tumours). I play drums and ride a motor bike too and this keeps me "up there".
