Serial faller-over. Low knee lift. My local parkrun has lots of tree roots and, thankfully, is often muddy, which makes for a softer landing. The worst fall of all on that route has been a 70-something male runner, who managed to break his collar bone - not very pleasant.
Actually, if you look at the history of Kids Company - the charity founded by Camila Batmanghelidjh to give her her proper name - it identified a pressing need and did good work, which was why successive governments gave it support. She certainly grew too big for her boots and didn't pay attention to maintaining reserves, but bent is a wee bit strong. Anyway, the simple truth is that most charities carry on doing what works for them - if it brings money in, they'll carry on doing it. That's why there are still chuggers - we all say we hate them, and yet enough people seem to hand over their details to make it worth their while to, mainly, pay agencies to do the work. I think the same goes for marathons and other events. You also cannot underestimate the 'brand awareness' charities get from being there at national, televised events. Anyway, handing over £50 - I can remember a time when people were saying 'don't give beggars money; give it to a charity that helps beggars'. You really can't win either way.
Surprise surprise, charities have overheads and pay their staff. Whatever next. What you could do, if you really wanted, is check out the accounts of a particular charity and try to work out if in your mind it gives enough of what it raises to the cause. Most of them spare the vast majority of what they raise for that. Bear in mind that any charity that says it gives 100 per cent of what it raises to its beneficiaries is either lying or... well, being economical with the truth. Phones, premises, staff don't cost nothing.
