I find increasingly as I get older (or maybe just less fit, as this doesn't seem to hit everyone equally) that a sudden increase in temperature makes alcohol a less and less good idea. A cool beer in the middle of the afternoon would have had me salivating in my twenties; it now has me anticipating an evening in which I'll be a bit drowsier than usual. Which is why I rarely touch the stuff before evening meal time.
I also don't drink when I'm out as often as I did. There are two reasons for this. First, in my day job I'm a jobbing journalist and in the past there have been a lot of occasions on which wine and beer has been on offer as part of a hospitality package - and I've found I'm very bad at finding the "no thanks" switch when I'm having fun. Second if I'm out during the day and someone offers me a glass of something and I take it, that's it - I can't and won't drive. Which, as I grow further into middle age, feels pretty much like an inconvenience.
So drinks like the above are more than welcome, less sugary than the fizz I grew up with as a child and with more actual fruit juice in them to boot. The charity angle is a bonus. If you're interested in that angle then do spare a thought for the male cancers as well, which are just as nasty but as yet not as well publicised. If you're a middle aged bloke - and that's who this blog is aimed at - or even a younger male, do yourself a favour and check your testes for unexpected lumps every so often; you can save not only yourself but your family absolute agonies if you find something before it develops too far.
