Went to the lake and did another pyramid session. 1-2-3-4-5-4-3-2-1 (minutes, that is, with walk breaks the same length between). Only I somehow managed to forget the 3-minute run on the way back down. Too much blood being demanded by the legs, not enough left for the brain.
Even allowing for the missing 3 minutes, it was slightly faster than the previous pyramid session, possibly thanks to the cheering effect of the sunshine. Wind is still cold, though.
My first mobile phone was brick-like, and my children used to laugh at it. It belonged to work, so had to go back when I retired; then I got one of my own. But that "died" recently and had to be replaced. I don't know how Red and BIW keep theirs going for so long. I only use mine for phone and text messages; don't take photos or pick up email, though it apparently has the facility.
And I do have a Satnav, though I haven't used it much. I don't like driving in areas I don't know, and will always go by train if the journey is feasible. The Satnav is very soothing and polite, and instead of saying "you idiot, I told you third exit" it says calmly, "When possible, turn round..."
