I retired, bought a cottage in the country and endured 3 years of building work - and then went into lockdown. Ah! peace at last... and over the last year my faded mousey- going -grey hair has steadily got browner and the grey is almost gone: a bit of a miracle. It's exciting getting up in the morning and peering into the mirror - and I am over 70, (hence the anonymous post). Go figure.
