I would either invest iun something safe (current economic climate permitting) or stick it in the bank and live of the interest. One of those or I would buy loads of penny chews.
Charity towards diseases where there is still no cure is a worthy cause...if you stick it in a bank someone might rob you...you need a bank with high security, yeah.
if you stick it in a bank no one will rob you, thats just stupid, the only one who could rob it in the bank are seriuos cyber terrorsists, or credit card banditd.
